The document discusses long-term preservation of 3D architectural data. It describes the DuraArk project which aims to develop methods and tools for sustainably preserving 3D architectural models over time. The challenges addressed include preventing information loss as buildings evolve, ensuring long-term readability of 3D models in the face of deprecated formats, and improving metadata schemes and vocabularies. The project brings together several partners to work on scientific excellence in long-term preservation, data integration, and 3D modeling of architectural structures.
Quality criteria for architectural 3D data in usage and preservation processeslindlar
Quality assessment of digital material has been just one of the new tasks the digital revolution brought into the library domain. With the first big print material digitization
efforts in the digital heritage domain dating back to the 1980ies, plenty of experience has been gathered and recommendations on best-practise published. Along the same line, libraries of today may often publish guidelines on formats or quality parameters for digital textual materials which enter their holdings.
While digital texts such as e-journals are in common use today, non-textual materials of various domains are just entering the holdings of cultural heritage institutions. An
example for this is architectural data, which is of interest to a variety of libraries and archives – ranging from special collection libraries, such as the RIBA Library of the
Royal Institute of British Architects, to national archives responsible for the archival of information about publically funded buildings. Architectural practise of today
commonly includes 3D object processing. The output of these processes is slowly reaching the aforementioned cultural heritage institutions which are now facing the task
of quality assessment of the material.
The presentation will present a first analysis of potential quality factors and compare architectural and cultural heritage domain expectations in 3D data quality. It will look at two forms of 3D data: modelled 3D objects and scanned 3D objects. The work presented in this presentation is based on work conducted in the ongoing EU FP-7 DURAARK project.
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.

Pre-Ingest workflows are comparatively new to the digital preservation domain – while the main focus of earlier efforts has been put on the needs of the organization / the repository which is responsible for the long-term stewardship of objects, questions around earlier processes have been arising only recently. Due to this “pre-ingest” dependencies and implications are not explicitly covered in standards like the OAIS or in PREMIS. The question is how information about the external pre-ingest service can be described meaningfully to the repositories and what level of granularity is called for. The DURAARK project has explored this subject with a planned PREMIS implementation in the DURAARK workbench, which covers pre-ingest tasks for architectural 3D data. The presentation highlights 3 central questions that arose in connection to the PREMIS implementation.
A Mapping-Based Framework for the Integration of Machine Data and Information...heigoo
This document presents a mapping-based framework for integrating machine data and information systems. The framework uses a declarative mapping language to describe transformations between different data schemas. Mappings are stored in a repository and can be reused. Code generators produce integration code from the mappings. The approach was evaluated using cases integrating machine sensor data in XML and CSV formats. The mapping language was found to be suitable but could be improved with more expression capabilities. Semi-automatic mapping reuse was successful, but fully automatic reuse remains challenging.
Metadata, the CARARE aggregation service and 3D ICONS3D ICONS Project
The document discusses the CARARE project, which aims to aggregate cultural heritage metadata from various European organizations and make it available through Europeana. It develops an intermediary metadata schema to help partners map their native schemas to Europeana's requirements. Partners use tools like MINT to map metadata to CARARE's schema, which is then transformed to Europeana's EDM schema for harvesting. While technical challenges remain, the project helps overcome differences in partners' systems to provide enriched metadata at Europeana.

A Scalable Approach for Efficiently Generating Structured Dataset Topic ProfilesBesnik Fetahu
The increasing adoption of Linked Data principles has led
to an abundance of datasets on the Web. However, take-up and reuse is hindered by the lack of descriptive information about the nature of the data, such as their topic coverage, dynamics or evolution. To address this issue, we propose an approach for creating linked dataset profiles. A profile consists of structured dataset metadata describing topics and their relevance. Profiles are generated through the configuration of techniques for resource sampling from datasets, topic extraction from reference datasets and their ranking based on graphical models. To enable a good trade-off between scalability and accuracy of generated profiles, appropriate parameters are determined experimentally. Our evaluation considers topic profiles for all accessible datasets from the Linked Open Data cloud. The results show that our approach generates accurate profiles even with comparably small sample sizes (10%) and outperforms established topic modelling approaches.

Turning Data into Knowledge (KESW2014 Keynote)Stefan Dietze
The document discusses turning data into knowledge through profiling and interlinking web datasets. It covers recent work on linked data exploration, discovery, and search including entity and dataset interlinking recommendations and dataset profiling. It also discusses ensuring data consistency and resolving conflicts. The document then examines challenges with reusing and interlinking the long tail of linked datasets and issues regarding structure, semantics, interlinking, and persistence of linked data on the web.
The document discusses curating and profiling linked data for educational applications. It describes the LinkedUp project, which aims to advance the use of open data and linked data technologies in education. The LinkedUp approach involves collecting and exposing open educational datasets, profiling the datasets to generate metadata, and linking datasets to create an "educational data graph." The profiling process extracts topic information from datasets by identifying entities, normalizing categories, and computing relevance scores to generate structured dataset profiles. This facilitates browsing, exploring, and querying across educational linked datasets.

It also discusses research areas like web science, information retrieval, and semantic web technologies. Some specific projects are mentioned for dataset profiling, entity linking, and generating structured topic profiles for datasets. Challenges around semantics, schemas, data consistency, and disambiguating entities are also outlined.
Libraries in the Big Data Era: Strategies and Challenges in Archiving and Sha...Peter Löwe
Peter Löwe presented strategies and challenges for libraries in archiving and sharing research data in the big data era. He discussed the Technische Informationsbibliothek (TIB) which provides access to over 9 million items and its strategy to move beyond just text by developing services for audiovisual and other types of big data. Löwe summarized TIB's use of Digital Object Identifiers (DOIs) and ORCID IDs to provide foundational infrastructure for open science. He also presented the Research Data Repository (RADAR) project and discussed future scenarios for libraries, including the roles of data scientists and potential mergers between libraries and computation centers.
Profiling vs. Time vs. Content: What does Matter for Top-k Publication Recomm...MOVING Project
So far it is unclear how different factors of a scientific publication recommender system based on users' tweets have an influence on the recommendation performance. We examine three different factors, namely profiling method, temporal decay, and richness of content. Regarding profiling, we compare CF-IDF that replaces terms in TF-IDF by semantic concepts, HCF-IDF as novel hierarchical variant of CF-IDF, and topic modeling. As temporal decay functions, we apply sliding window and exponential decay. In terms of the richness of content, we compare recommendations using both full-texts and titles of publications and using only titles. Overall, the three factors make twelve recommendation strategies. We have conducted an online experiment with 123 participants and compared the strategies in a within-group design. The best recommendations are achieved by the strategy combining CF-IDF, sliding window, and with full-texts. However, the strategies using the novel HCF-IDF profiling method achieve similar results with just using the titles of the publications. Therefore, HCF-IDF can make recommendations when only short and sparse data is available. http://arxiv.org/abs/1603.07016
This presentation discusses the importance of long-term preservation and access to research data. It notes that current research data management faces risks like loss of data and metadata over time. Preserving data has value for verification, knowledge transfer, and continuing research. The 3TU.Datacentrum project aims to build a repository for research data from three Dutch universities to enable long-term access. It is collecting and preserving datasets and providing data management services and advice to data producers. Workshops with data producers found support for the repository but also concerns about confidentiality, resources, and responsibilities.
Enabling Data-Intensive Science Through Data InfrastructuresLIBER Europe
These slides are from a talk given at LIBER's 42nd annual conference by Carlos Morais Pires of the European Commission.
In light of the current data deluge, and plans by the European Commission to harness this deluge through the implementation of e-infrastructures for data driven science under Horizon 2020, Pires issued a call to action to libraries to engage in the data infrastructure and bring their own unique, and now much needed competencies, to bear in bringing meaning to, and spreading the word about, data-driven science.

IFLA ARL Webinar Series: Digital Preservation - Managing Publications and Dat...IFLAAcademicandResea
This webinar gives a comprehensive overview of the basics of digital preservation, and a more in depth account of challenges regarding research data in this field.
During the last decade several projects with respect to digital preservation have been funded in Europe by the European Commission and have delivered interesting results. Such projects include community building projects or coordination actions such as ERPANET, Delos2, and Digital Preservation Europe (DPE), but also research projects such as Planets, CASPAR, Shaman, Protage. In December 2009 a new call for digital preservation will be closed, so new projects may start in 2010.
One result of all these projects and all the work done is that there is a growing community involved, more organizations and people are aware of the issues, definitely has enhanced the collaboration amongst institutions and universities in Europe, and with the last research projects some potential practical solutions are emerging that could be applied by institutions. How it all will work out in the end is still one of the big questions. For one thing it may have helped to create a good foundation for further collaboration, perhaps even without funding from the European Commission.
This presentation will provide a brief overview of the main results of some of these projects, especially Planets, and what issues they try to resolve, and a brief outlook on possible future developments.
This document summarizes a 4-year EU-funded project called PERICLES that involves 11 partners. The project addresses the challenge of long-term access to digital content as environments continually evolve. It recognizes that the meaning and understanding of digital objects depends not only on the objects themselves but also on the evolving environments in which they were created. The project is developing tools and models to extract, represent, and encapsulate information about dynamic preservation ecosystems in order to better support the long-term reuse of digital content over time. It is currently halfway through and has made progress on describing digital ecosystems and dependencies, as well as seeking feedback on its approaches to environment extraction, encapsulation, and appraisal.

Transforming repositories: from repository managers to institutional data man...JISC KeepIt project
The last decade has seen support for digital preservation transformed. There are now a multitude of organisations, training courses, and software development tools to help guide managers of digital data towards preservation decisions and solutions. But how well do these approaches understand the needs and requirements of users? This presentation was given at ECA 2010, a conference for digital archiving professionals. But not everyone can be a digital archiving specialist. At a time of exploding volumes of digital content, especially on the Web, many non-specialists need help in preserving digital content. The presentation looks at the applicability and practicality of all this support for one class of user, digital repositories, and in particular institutional repositories (IRs) and their managers. We report on a course on digital preservation tools, designed by repository managers as part of the JISC KeepIt project. Positive feedback from the evaluations of this course have show that the emergence of the tools used in this course is a great story for digital preservation.
Digital preservation of scientific and cultural heritage is important but faces challenges. A proposal is made for India to:
1) Digitize fragile magnetic recordings from geomagnetism research to ensure long-term access and analysis.
2) Develop a national strategy for digital preservation including legal policies, training, and research to ensure long-term access to digital resources.
3) Leverage the OAIS reference model and form collaborations between libraries, archives, and data centers to establish best practices for the preservation of India's digital heritage.

Tangible outcomes
LinkedUp in a nutshellTangible outcomes
Tools for detection of changes in the building: Avoid
information loss by detecting differences in original
building plans and point clouds documenting the as-is
building state to enable guided repair
OAIS compliant storage: Face problem of digital decay
by using Industry Foundation Classes (IFC) as an open
and already well-established file format suited for
long-term preservation. Use point cloud compression
techniques that are self-documenting and robust
towards bit rot.
Tailored Workflows: Thoroughly investigate
requirements of institutional stakeholders
(libraries/archives) and SMEs on long-term archiving.
Develop according workflows.

Digital preservation and 3D
architectural data
19. 19 / 33 30 / 04 / 13 Dr Helmi Ben Hmida (Leibniz University Hanover, DE)
• Creating technology solutions and innovative methods for keeping 3D
architectural data available and useable over time
• Implement approach based on the OAIS model to support the 3D
architectural data
• OAIS
• Archive consisting of organization, people and systems
• The primary goal of an OAIS is to preserve information for a
designated community over an indefinite period of time.
• OAIS must store significant information about the object and its
contents.

The 3D architectural data
• Be based on the Industry Foundation Classes (IFC)
• Study and suggest different criterion to evaluate 3D data
structure and their related risk for preservation purpose.
• Study several kinds of 3D data structure add to the IFC
and evaluate it based on the selected criterions (CAD,
IFD, WRL…)
