A standard recommendation for Digital Pathology Information Web-Services. A novel recommendation for the Digital Pathology Information Web-Services (DPIWS) standard is presented, with respect to specific characteristics of the informative content of discourse. The recommendation establishes a common software interface for the exchange of digital pathology (DP)images and related metadata over the web, independently of storage, encoding, and internal handling details. Thepro-posed structure is implemented and tested in a “Pathomation”software environment.
Presentation by Franco Niccolucci, Andrea D'Andrea and Sheena Bassett about the 3D ICONS project given at VSMM 2012. 3D ICONS is digitising world heritage sites in 3D and preparing content for publication online to be made available via Europeana.
Part 1 of the printed publication "3D-ICONS Guidelines and Case Studies" First published in November 2014.
Public fascination with the architectural and archaeological heritage is well known, it is proven to be one of the main reasons for tourism according to the UN World Tourism Organisation. Historic buildings and archaeological monuments form a significant component Europe’s cultural heritage; they are the physical testimonies of European history and of the di°erent events that led to the creation of the European landscape, as we know it today.
The documentation of built heritage increasingly avails of 3D scanning and other remote sensing technologies, which produces digital replicas in an accurate and fast way. Such digital models have a large range of uses, from the conservation and preservation of monuments to the communication of their cultural value to the public. They may also support in-depth analysis of their architectural and artistic features as well as allow the production of interpretive reconstructions of their past appearance.
The goal of the 3D-ICONS project, funded under the European Commission’s ICT Policy Support Programme which builds on the results of CARARE (www.carare.eu) and 3D-COFORM (www.3d-coform.eu), is to provide Europeana with 3D models of architectural and archaeological monuments of remarkable cultural importance. The project brings together 16 partners (see appendix 2) from across Europe (11 countries) with relevant expertise in 3D modelling and digitization. The main purpose of this project is to produce around 4000 accurate 3D models which have to be processed into a simplified form in order to be visualized on low end personal computers and on the web.
This presentation was presented at the IGeLU conference in Oxford, UK. It introduces the audience into the EU funded research project DURAARK and gives an insight for the first archieved goals and next steps concerning the preservation of three dimensional architectural data.

The Visual Media Service (VMS) provided by the ARIADNEplus Project enables large datasets to be processed and displayed seamlessly and quickly, enabling end users to view and explore in detail:
3D objects ranging from size from a few mm to tens m, e.g. from beads up to statues and friezes.
Large, high resolution images (that can’t usually be easily displayed online), e.g. gigapixel photographs of frescoes, paintings, or any other planar artwork.
Relightable images (RTI and PTM) commonly used on artefacts such as coins.
Sets of images such as a time series or sequence of pages relating to the same item.
The VMS technology provides a full set of interactive tools for the displayed object(s) and can be accessed for free through the ARIADNE Portal. As such, this service provides a valuable tool for the publication, exploration and dissemination of various aspects of Cultural Heritage.
DANS Data Trail Data Management Tools for Archaeologistsariadnenetwork
With the arrival of ARIADNEplus there is a searchable catalogue of datasets that helps archaeological researchers navigate the “maze” of data and archives. Especially for archaeological researchers, support staff and data managers, a set of tools has now been developed that helps in making your data management plan. Hella Holander, Peter Doorn and Paola Ronzino introduced the tools to the participants during the workshop.
The ARIADNEplus online toolset for data management consists of three parts:
a protocol for archaeological data management,
a template for researchers to create a data management plan with archaeological data,
a manual containing all guidelines, recommendations and practical examples of data management.
In just six steps, the protocol takes you through the entire process of making a Data Management Plan (DMP) for archaeological research. By using the templates and the accompanying manual with a clear set of guidelines and advice, it becomes much easier to meet the requirements of organisations that fund research. The DMP is then also in line with standards in the archaeological domain, which ultimately makes the data more findable, accessible, reusable and interoperable (FAIR).

To promote open science and data reuse, it is necessary to have data available in open repositories that guarantee their accessibility and permanence, while facilitating their reuse.
Data classified as FAIR (Findable, Accessible, Interoperable and Reusable) must follow guidelines that ensure the use of an appropriate metadata scheme, persistent identifiers, well-defined vocabularies, procedures to standardize and improve data quality and sustainable file formats. We will present the methodology used for recording the coin findings from an archaeological excavation carried out by the Archaeology Unit of the University of Minho (UAUM) in the intervention of Casa da Bica, starting with the recording of data in the UAUM's 2ArchIS information system and ending with its availability in the scientific repository "DataRepositóriUM". We will also present some works of visualization and research as examples of the reuse of these data sets, which can be wider when they are integrated in structures of greater visibility like ARIADNE.
On one hand, COVID-19 world pandemic showed the people vulnerability and inability of face-to-face communication and ideas sharing. Through this point of view digital data that is Findable, Accessible, Interoperable and Re-usable (FAIR) showed its added value in even higher extent. On other hand, online communication became a daily routine enabling easier access of all interested parties regardless of their location. The latter helped focusing on particular tasks difficult to accomplish otherwise. The situation in Bulgaria concerning improving state-of-the-art of site and monument dataset “Archaeological Map of Bulgaria” is still in a work process based on online communication with interested participants. Scientists from the National Archaeological Institute with Museum at Bulgarian Academy of Sciences are responsible for all that. Legacy data available beyond local repositories using FAIR principles is a main focus in the development and up-to-date improvement. Sharing the most informative fields metadata and available digital data in ARIADNE portal enabled cleaning other issues in the information system.
This contribution will present digital assets and initiatives at the Museum of Cultural History (MCH), University of Oslo (UiO) and aims at sharing data. The COVID-19 restrictions have elevated the importance of digital assets. At the beginning of this period, metadata for the archaeological collections were, to a large
degree, already digitized and accessible online. This is the result of a national collaboration beginning in the 1990s and continue today in UniMus:Kultur. MCH had also published a map-based overview of all excavations in Eastern/Southern Norway, and
begun to release excavation reports through UiO’s science archive. Recently, focus has shifted towards 3D-documentation of exhibits and publication of existing 3D-models on 3DHOP—available through humgis.uiocloud.no MCH now concentrates on digitizing artefacts at the Viking Ship Museum. The 3D-models
from here will be included in the BItFROST project, which will address the active role of 3D-models in research and education. BItFROST will work on FAIRifcation of 3D-models and promote dialogue with researchers. The 3DHOP platform enables the creation of interactive user-interfaces for researchers and a public audience. Collaboration with DarkLab in Lund, Sweden will create common user-interfaces for Swedish and Norwegian
collections. The project will also utilize AR and VR in the presentation of data.
In addition, the infrastructure project ADED (Archaeological Digital Excavation Documentation) provides open-access to excavations in Norway. The five Norwegian university museums and the Directorate of Cultural Heritage take part in the project.
ADED’s map-based webpages will integrate excavation documentation and the museums’ artefact/photograph databases, making it possible to have an overview and
detailed information of excavations and finds. As part of migrating the data to a common repository, mapping it to CIDOC-CRMarcheo facilitates further mapping to ARIADNEplus and/or other datasets.
Abstracts for the ten presentations at EAA 2021 Session 476: Understanding and expanding capacity in archaeological data management beyond western Europe organised by ARIADNEplus and SEADDA under Theme 3: The new normality of heritage management and museums in post-Covid times on 8th September 2021.
Eaa2021 476 ways and capacity in archaeological data management in serbiaariadnenetwork
Over the past year and due to the COVID-19 pandemic, the entire world has witnessed inequalities across borders and societies. They also include access to archaeological resources, both physical and digital. Both archaeological data creators and users spent a lot of time working from their homes, away from artefact collections and research data. However, this was the perfect moment to understand the importance of making data
freely and openly available, both nationally and internationally.
This is why the authors of this paper chose to make a selection of data bases from various institutions responsible for preservation and protection of cultural heritage, in
order to understand their policies regarding accessibility and usage of the data they keep. This will be done by simple visits to various web-sites or data bases. They intend to check on the volume and content, but also importance of the offered archaeological heritage. In addition, the authors will estimate whether the heritage has adequately been classified and described and also check whether data is available in foreign languages. It needs to be seen whether it is possible to access digital objects (documents and the accompanying metadata), whether access is opened for all users or it requires a certain
hierarchy access, what is the policy of usage, reusage and distribution etc. It remains to be seen whether there are public API or whether it is possible to collect data through API.
In case that there is a public API, one needs to check whether datasets are interoperable or messy, requiring data cleaning.
After having visited a certain number of web-sites, the authors expect to collect enough data to make a satisfactory conclusion about accessibility and usage of Serbian archaeological data web bases.
Eaa2021 476 izeta cattaneo idacordig and suquiaariadnenetwork
The COVID-19 pandemic unleashed during 2020 implied a change in the way of doing archaeology on a global scale. In Argentina, in particular, activities had to move to the
domestic sphere and, most times, the possibility of carrying out fieldwork, material analysis and collection management in the usual workplaces was lost. This practice showed the need for repositories, libraries and online databases that would allow access to archaeological information. Suquía, the institutional repository of IDACOR, has been compiling and disseminating archaeological information since 2016, although it had not
yet developed its capacity to include databases that would allow meta-analysis of the information hosted. So, the needs raised by the lockdown led to implementing an action aimed at incorporating data from 1938 archaeological sites in the Province of Córdoba (Argentina) together with IDACORDIG (an implementation of the Arches software) which links this set to a spatial database, creating a gazetteer of archaeological sites for the region. This integration is the first of its kind in Argentina, and fosters an increase in primary information and grey literature visibility, together with publications preprints and
prints that allow continuity in the study of archaeology on a regional scale. In this presentation we will characterize this process and its technical aspects to aware on the potential of this type of platform for its integration into digital infrastructures of global impact.
Eaa2021 476 preserving historic building documentation pakistanariadnenetwork
Like many countries around the world, Pakistan was forced to go into a COVID-19 national lockdown in March 2020. While this confined most people to their homes, it also had the unintended consequence of catapulting many institutions into embracing going digital. At the National College of Arts (NCA), Pakistan’s oldest art school, this meant embracing online tools and digital resources that had previously been resisted or under utilized in the teaching of art, design, and architecture. The experiences of
lockdown have highlighted inadequacies and inequities within our systems, and as Pakistan returns to normal there is a renewed will to maintain the momentum gained during the pandemic, and an increased realization of the need for developing and sustaining digital infrastructures. The National College of Arts Archives collect and preserve the records, manuscripts, and other artefacts of historical and archaeological
significance at the National College of Arts. From March 2021, the NCA Archives are initiating a project to collect, preserve, and digitize historic building documentation created at the NCA over the past 145 years. This paper will follow this process and
document the NCA Archive’s attempt at creating a Findable, Accessible, Interoperable, and Reusable (FAIR) database of historic building documentation in Pakistan. It will summarize the experiences of the six-month pilot project, including opportunities that have arisen in the aftermath of the Covid-19 pandemic, and in light of the Government of Pakistan’s ongoing Digital Pakistan initiative. The paper will also document and analyze the difficulties and hurdles that might emerge during the course of the project as the NCA Archive’s digital infrastructure is built from the ground up in a post-colonial setting and a post-COVID world.
The COVID-19 pandemic has exacerbated or made more visible many known inequalities across borders and societies. This includes access to archaeological resources, both physical and digital. As both the creators and users of archaeological data adapted to working from their homes, cut off from artefact collections and research data siloed within organisations and institutions, the importance of making data freely and openly
available internationally became even more pronounced. The ARIADNE infrastructure (ariadne-infrastructure.eu) for archaeological data, and the SEADDA COST Action
(seadda.eu) are working to secure the sustainable future of archaeological data across Europe and beyond, in ways that are Findable, Accessible, Interoperable and Re-usable (FAIR). Experience within the ARIADNE partnership during the pandemic was largely positive, with many partners able to carry on as usual with accessing their digital resources, emphasising what is possible, while also emphasising what is not achievable
across archaeology, due to lack of capacity. ARIADNE and SEADDA invite papers discussing the challenges, opportunities and lessons learned across all aspects of archaeological data management during the pandemic, and how it may change and
inform our best practice going forward. We particularly invite papers from outside of Western Europe on how the COVID-19 pandemic created barriers or opportunities for accessing archaeological resources, so that we may better understand capacity building during a post-COVID era.
The Portable Antiquities of the Netherlands (PAN) portal and the data model behind the description of the findings are discussed in detail, and how this approach leads to publishing data that is FAIR .
The Innovation Strategy and Targeted activities report presents the ARIADNEplus innovation strategy, addressing its different dimensions and how each of these will approached.
The main dimensions of the strategy are:
Research policies: Alignment with the European research policies on FAIR data, Open Science practices, and the European Open Science Cloud (EOSC) initiative.
Data integration: Increase of the ARIADNE data pool through incorporation of datasets from more archaeological research domains.
Data infrastructure: Implementation and operation of a Cloud-based platform for data aggregation, integration, discovery, access and use across across institutional and national, as well as disciplinary boundaries.
Service portfolio: Provision of enhanced and new services for digital archaeology on the Cloud-based platform.
Stakeholder and user base: Extension of the stakeholder and user base in Europe and beyond, taking account of user needs regarding data, technical services and training.
The report concludes with the methodology that is being used to evaluate the impact of ARIADNEplus on the wider archaeological community.
The objectives for the ARIADNEplus online survey were to collect information on needs of the ARIADNEplus user community regarding data sharing, access and (re)use, new services (as developed by the project), and related training needs. Results of the ARIADNEplus survey were to be compared, where possible, to those of the ARIADNE 2013 survey (ARIADNE 2014) and, particularly, to planned new technical and other services. Furthermore, the analysis of the results had to focus on the match between the perceived user needs and planned ARIADNEplus services, and suggestions to be provided on activities likely to enable an optimal match.
This presentation provides an insightful view in the process of digitising agenda in Czech archaeology. A cornerstone of this is the Archaeological Information System of the Czech Republic (AIS CR), a national solution for research management, data gathering, curation and presentation. A key component AIS CR is the Archaeological Map of the Czech Republic (AMCR), operational since 2017.
OpenArchaeo is an application to query archaeological data via CIDOC CRM developed by the MASA Consortium (Mémoire des archéologues et des sites archéologiques). This exciting tool allows to query both the MASA triplestore and other sources of archaeological data mapped with the CIDOC CRM and can be used by other interfaces such as the ARIADNE portal.
INRAP is one of the biggest European institutions in charge of unmovable archaeological heritage. Although centralised, INRAP is so big that a lot of diversity in terms of standards and tools existed. Therefore, ARIADNE was very helpful for Kai, Amala and their co-workers to apply some of the ARIADNE’s tools and approaches to INRAP. One of the top achievements of INRAP due to ARIADNE was ‘changing the culture of sharing’.
DANS, the Dutch Data Archiving and Networked Services provides facilities for the deposit and archiving of archaeological data and provide a Trusted Digital Repository. Challenges involved mass ingestion of datasets and making use of thesauri, data mining and Linked Open-Data techniques.
The Swedish national Data Service (SND) were in the original ARIADNE project and learned how to organise and classify their data for both the Portal and their own web service. Able to display map, marker and polygon information now. Use Elasticsearch, AAT and Periodo.
Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.
Data Centers - Striving Within A Narrow Range - Research Report - MCG - May 2...pchutichetpong
M Capital Group (“MCG”) expects to see demand and the changing evolution of supply, facilitated through institutional investment rotation out of offices and into work from home (“WFH”), while the ever-expanding need for data storage as global internet usage expands, with experts predicting 5.3 billion users by 2023. These market factors will be underpinned by technological changes, such as progressing cloud services and edge sites, allowing the industry to see strong expected annual growth of 13% over the next 4 years.
Whilst competitive headwinds remain, represented through the recent second bankruptcy filing of Sungard, which blames “COVID-19 and other macroeconomic trends including delayed customer spending decisions, insourcing and reductions in IT spending, energy inflation and reduction in demand for certain services”, the industry has seen key adjustments, where MCG believes that engineering cost management and technological innovation will be paramount to success.
MCG reports that the more favorable market conditions expected over the next few years, helped by the winding down of pandemic restrictions and a hybrid working environment will be driving market momentum forward. The continuous injection of capital by alternative investment firms, as well as the growing infrastructural investment from cloud service providers and social media companies, whose revenues are expected to grow over 3.6x larger by value in 2026, will likely help propel center provision and innovation. These factors paint a promising picture for the industry players that offset rising input costs and adapt to new technologies.
According to M Capital Group: “Specifically, the long-term cost-saving opportunities available from the rise of remote managing will likely aid value growth for the industry. Through margin optimization and further availability of capital for reinvestment, strong players will maintain their competitive foothold, while weaker players exit the market to balance supply and demand.”
Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

images
(high-‐res!)
• Advanced2D
images
(PTM,
RTI,
panoramic
images,
HDR)
• 3D
models
(single
or
complex
scenes)
• Videos
• GIS
data
6. Goals
of
the
TNA
on
2D/3D
media
• General:
enable
scholars
and
professionals
to
endorse
and
implement
modern
approaches
for
the
visual
mulDmedia
documentaDon
of
artworks
and
archaeological
sites
(i.e.
fieldworks
and
artefacts)
• More
specifically:
pair
classical
frontal
lessons
with
a
more
pracDcal
acDvity
(hands-‐on
experience
on
the
technologies
presented)
7. Goals
of
the
TNA
on
2D/3D
media
• Prac-cal
ac-vity:
– We
solicited
parDcipants
to
submit
specific
problems
and
test
cases
they
are
working
with
– These
test
beds
were
an
important
criterion
in
the
selecDon
of
the
parDcipants
– Program
of
the
school
included
Dme
dedicated
to
advising
the
students
on
the
pracDcal
hands-‐
on
experience
and
in
their
proposed
case
studies
8. Selected
students
• Eleven
parDcipants
– 9
were
assigned
an
ARIADNE
fellowships
and
2
come
at
their
expenses
– from
several
different
countries
(ArgenDna,
Belgium,
Estonia,
Germany,
Greece,
Italy,
Netherlands,
UK)
– Holding
a
mixed
background
(in
the
majority
a
human
science
background,
only
a
few
holding
an
engineering
degree)
9. Lesson
learned
(WS
&
TNA)
• Good
experience
in
produc-on
of
visual
media
(mostly
2D,
but
also
some
high-‐profile
3D
acDvity)
– CNR
offers
support
in
this
acDvity
(open
source
tools)
• Cri-cal
issue:
Archival
and
Access
to
visual
media…
10. Lesson
learned
(WS
&
TNA)
• 2D
images
are
stored
and
integrated
with
in
Ariadne
partner’s
archives
/
databases
• 3D
models
are
sDll
isolated
resources
• Access
is
the
problem:
– SDll
managed
as
“data
files”
– Approach
used:
• NoDfy
existence
of
the
data
file
of
a
visual
media
resource
• User
downloads
the
file
(Dme
lag)
• User
needs
to
have
an
applicaDon
for
managing
that
file
type
(error
messages)
11. Lesson
learned
(WS
&
TNA)
Problems
with
data
file
approach:
• Explicit
download
and
file
size
– Files
of
visual
media
assets
are
usually
large/huge
• 2D
image
in
high-‐res
(40Mpixels)
è
120MB
uuncompressed,
15
MB
lossy-‐compressed
• 3D
model
(scanned)
is
mulit-‐million
triangles/samples
è
from
50MB
to
GBs
– Should
we
wait
for
enDre
file
transfer
comple-on
before
looking
into
the
data
(and
discover
that
is
not
the
one
we
are
searching
for)?
12. Lesson
learned
(WS
&
TNA)
Problems
with
data
file
approach:
• Once
file
is
on
local
disk,
do
I
have
an
applicaDon
to
open
it?
– Many
different
file
types
(easier
with
images,
highly
complex
with
3D
models)
– The
deprecated
error
message:
• Unrecognized
file
type
13. Modern
access
to
visual
data
• The
web
is
the
channel:
– Click
and
immediately
inspect
the
data
– Inside
current
web
page
or
into
a
new
one
– Using
your
favourite
web
browser
– Possible
with
many
visual
media
using
WebGL
and
modern
support
to
data
– How
can
we
help
our
community
to
integrate
those
technologies
in
exis+ng
archives
/
databases?

16. New
ARIADNE
services
for
visual
data
Our
idea:
• For
each
visual
media
asset:
– The
user
fills
a
simple
form
and
uploads
the
data
file
– An
automa-c
service
on
the
ARIADNE
server
will
open,
convert,
transform
in
a
browsable
page,
send
in
output
the
URL
(or
a
.zip
file)
to
the
user
– The
user
links
the
media
asset
in
his
archive
using
the
provided
URL
17. New

ARIADNE’s
umbrella
• Several
technological
instruments
presented
extensively,
on
real
archaeological
examples
and
with
prac-ce
• Feedback
gathered
instrumental
to
the
design
of
