• from 2019: A department in VIAA - Flemish Institute for Audiovisual Archiving
• Flemish, Belgian and European projects
• Support for ICT-processes at heritage and arts organisations (o.a. creating, storage,
cataloguing, online access, exchange and reuse) and policy thereof
• Central concern: sustainability (digital heritage is vulnerable)

Programme ‘Shifting minds’ session
- PACKED:
- Open GLAM community: International and in Belgium
- PACKED: open data projects: persistent identification and publishing of data
- PACKED: advocacy en training
- Conclusions and wishlist
- Use cases from the cultural heritage sector:
- Wikimedia publication of King Baudouin Foundation collections - Olivier Van
D’huynslager
- Flemish Art Collection: Arthub/Datahub - Matthias Vandermaesen
International OpenGLAM community
OpenGLAM in Belgium
Infrastructure for open data in the cultural sector
Data:
- Messy and not complete, but a lot of potential knowledge
- Captured on different carriers (systems, digital and analogue files)
- Often closed (and obsolete) software
- ‘4-star’ data is becoming reachable for the cultural heritage sector
- ‘5-star’ Linked Open Data: persistent URI’s solution?
Publishing:
- Where? Own platforms vs existing Open Data Repositories
Infrastructure: Persistent URI’s
- Nobody knows what PIDs are and why you should use it
- Not that obvious in the cultural heritage sector
- Not just a standard part of the used collection mgmt systems,
- Not just something that you ask your IT to configure (because there is no IT)
- PID-projects (2013-2016) - Resolver-tool v1
- Open Summer of code 2018 - redevelopment
What is cultURIze?
Culturize is a tool for museum administrators to share data about
their collection using persistent URI’s.
Who needs CultURIze?
Registrars, curators and managers of small or medium cultural heritage
collections.
https://github.com/PACKED-vzw/CultURIze
https://github.com/PACKED-vzw/CultURIze/wiki
- prototype developed during Open Summer of code 2018 in Belgium
- inspired by W3id on Github
How does it work?
CultURIze is four-step process to create a persistent URI for a collection
item on the web:
- Record persistent URI's and the corresponding webresources in a
spreadsheet
- Turn the spreadsheet into a server configuration file
- Upload the file to a code sharing platform
- Periodically update your webserver to activate the persistent
URI's.

2019: Governance and contribution project
- Research on a sustainable governance model for the CultURIze
project.
- How to generate financial means and create a community of
developers around the CultURIze?
- Partners:
- Open Knowledge Belgium
- Flemish Art Collection
- Flemish Architecture Institute

Challenges for LOD in cultural sector
digital movement <> no digital mindset
reducing costs <> out-of-control IT-budgets
new ‘digital’ audiences <> losing ‘traditional’ audiences
showing off with fancy tools <> locked up in obsolete technology
engaging with the ‘crowd’ <> abandoned web portals
Wishlist
● More IT profiles in the cultural heritage sector and less dependence on the providers
● More freedom to play around and test things out
● Better open infrastructures and tools that make better internal workflows and LOD
possible:
○ Back office tools: Collection Management Systems, DAMs , Datahubs…
○ Publishing online tools: Resolvers, API’s...
○ Reusing: Wikimedia art viewers, apps...
○ etc...
● Vocal and demanding audience:
○ curating/enriching data
○ (examples of) reuse:
■ ie. unisex Hokusai kimono by Noir Noir
In 2019 PACKED wants to continue to push for open data in the heritage sector:
● Projects:
○ Projects which pool resources for infrastructure on a sector-wide scale:
■ Option 1: sharing ‘one big machine’
■ Option 2: ‘networked’ infrastructure - several machines talk to each other
○ Structured Data on Commons pilots
○ Public domain publication
○ Multilingual information museums of Bruges
○ ...
● More focus on training, institutions publish LOD (semi-)autonomously
Do you see yourself contributing to one of the projects or to the wishlist?

King Baudouin Foundation and Wikimedia
Infrastructure at the King Baudouin Foundation
- Messy and incomplete data
- Works in collection are dispersed over 80+ institutions (depot).
- Registered differently according to its location
- Huge gap! (7000 records of aprox. 26.000 pieces)
- Shared in different ways
- Analog x digital (closed x open(?))
- Webportals
- DAMS
- Arthub
- Overall → DISPERSED
Challenges (case: Collection Van Herck)
- Collect data from various
sources:
- Sculptures and drawings
- 4 institutions (3 dutch / 1 french)
- Normalize data so the metadata
becomes linkable:
- inventory numbers from various
locations:
- CVH 11A(1)
- Inv 30A
- IB00.106

Who are we?
What we do?
Leveraging museal data is challenging
● Getting registration data out of collection management systems
○ No API’s (manual exchange)
○ Proprietary vendor formats
○ Legacy systems
○ Different institutions, different contexts.
● Quality of the data
○ Inconsistent registration (decades of organic growth)
○ No normalisation (no or limited authorities: VIAF, AAT, ICONCLASS,...)
● Which data to use?
○ Context dependent: online browseable collections.
○ Currently: Basic registration (24 base fields)
○ SPECTRUM 5.0: 21 procedures (Acquisition, Loan in/out, Condition,...)
Goals
● Automate sharing museal data between applications
○ Less time between registration and publishing online
● Connect complementary collections and museums
○ Fashion, Industry, Art, Folklore,...
○ Location and time period
● Audit museal data
○ Quality assessment v. digital (re)usability
○ Enrich data with external authorities (linked data)
● Open up collections
○ Publish museal data under Creative Commons licenses.
Milestones
The Big Picture
Arthub Flanders
● Online catalogue of the Flemish museums of Fine Arts and Contemporary Arts.
● Currently disseminates collections of:
○ Groeningemuseum (Bruges)
○ Museum of Fine Arts Ghent
○ Royal Museum of Fine Arts Antwerp
● Usable discovery interface
○ Search should yield relevant search results
○ Fast delivery of search results
○ Presentation should be usable for humans

The Datahub
● Aggregation
○ Central “hub” for collection records from different sources
● Persistent storage of a copy of the collection records
○ But NOT a collection management system.
● Publication of collection records via web services
○ Open protocols: HTTP REST API & OAI-PMH
○ Open formats: LIDO XML
The Datahub
The Datahub
ETL Pipelining
● Extract Transform Load
○ Fetch data from a source (database, flat file, API,...)
○ Transform the data (different format, different structure)
○ Load transformed data to a destination (database, flat file, API,...)
● A pipeline is actually an automated ETL process on a server
○ Reliable
○ Modifiable
○ …
● Mappings between CMS’es, The Datahub and Arthub Flanders
○ Based on context specific business rules
○ Only: Basic registration fields
○ Concerns: Security, Confidentiality, Privacy, Copyright.
http://librecat.org
Data Quality
● What does “Quality” mean?
○ Does the data yield relevant answers?
○ Can I import the data in my application?
○ Can I combine the data with other datasets?
○ Can I present the data with low effort?
○ ...
● Quality is context dependeable
○ Who uses the data? Museum workers, researchers, policy makers,...
○ Where is the data used? Exhibition hall, at home, at an office,...
○ When is the data used? Before a visit, during a meeting,...
https://dashboard.vlaamsekunstcollectie.be
Data Quality
● Digital usability
○ Findable
○ Analysable
○ Combinable
○ Storable
○ Trustworthy
● Metrics
○ Completeness
○ Unambiguity
○ Richness
○ Openness

○ https://iiif.io
● Expand towards other interested museums
○ Complementary collections in similar platforms
○ Requires further valorisation of collections out there
● Find new use cases for open museal data
○ Improve operations in museums themselves
○ Sharing knowledge with other organisations
○ Creative industries
○ Tourism & Marketing
○ ...
