The document discusses the Network War Collections project in the Netherlands, which aims to improve digital access to approximately 430 Second World War collections from 74 member organizations by collecting and enriching metadata and full content. The project has collected over 10 million WW2 objects from 256 collections so far. It is developing tools to automatically extract and enrich information like names, dates, locations and events from the data. The goal is to transform separate "web of documents" into interconnected "web of data" and eventually a semantic web to better enable computers and people to work together.

24. …to a ‘web of data’…

25. …to a semantic web
The Semantic Web is not a separate Web but an extension of the
current one, in which information is given well‐defined meaning,
better enabling computers and people to work in cooperation

26. Our sales pitch
- Increased visibility of your organization
- Learn more about your collection in the context of others
- Free enriched metadata!
- Help (fund raising, technical advice, etc).

27. Issues
- Copyright and privacy legislation
- Poor quality of metadata provided by GLAMs
- Collections are not core business for some organizations

28. Culture clash: ‘my’ collection

29. Cooperation is innovation because
- Together we know more
- Together we can do more
- Together we can offer a better user experience
