Public domain calculator
This document discusses the Public Domain Calculator project, which aims to determine the public domain status of creative works by country based on copyright laws. It notes that different institutions use different ontologies to represent metadata, making integration complicated. The project founders learned that knowledge representation depends on many contextual factors and is not static. They aim to grow the project by integrating with databases like Wikidata and developing new semantic technologies and "killer applications" to make the complex data more accessible and useful to end users.

- 2. Index • Whatis the Public Domain Calculator? • What did we learn doing it? • Where are we going with it?
- 3.
- 4. Mankind has spreadits knowledge all over the world without considering how in time technology (and lawyers) could have changed the interactions and the use and reuse of art and content
- 5. Institutions are collectingMetadata in semantic form... And many more to come...
- 6. ... Everyone withits own ontology • Europeana => custom ontology • BNF => custom ontology (with coverage of artists’ lifes) • CulturaItalia => Erlangen-CRM based ontology (why??) • Smithsonian => Europeana • OpenCultuurData => custom ontology
- 7. Copyright law makeseverything complicated (and is complicated)
- 8. Every country hasa different graph (very complex)
- 9. With very specificquestions
- 11. All in allthere are a LOT of questions
- 12. A graph madeof graphs made of.... Ok we need to stop. After 3 levels of abstraction it is almost impossible to manage complexity with the tools we have now
- 17. What did welearn? Let’s state even the obvious
- 18. Having a Hammerdoes not make everything a nail • Semantic technologies are fascinating • They are not the panacea • Perfect for knowledge representation • Not perfect for operation representation • Yet, operations are a form of knowledge • Yet, representing operations as semantic elements is complicated • Yet, there is an interesting task ontology • Yet unifying the representation of something practical is complicated
- 19. Knowledge representation isnot unique • The representation itself depends on • Historical moment • Cultural background • Complexity of the field • Common knowledge • Political context • Social context • Perceived and real relevance • Aim of the representation
- 20. Knowledge representation isnot final • We need tools to easily reflect the changing knowledge • As well as the fact that the knowledge itself changed
- 21. Oh, the Tools... • Working with Semantic technologies can be complex • Lots of Java stuff, some Python works, something in JavaScript • Lots too experimental, something too enterprisey • WE NEED MODERN KILLER APPLICATIONS!
- 22. Where are wegoing? And which way is the future?
- 23. PDCalc • Majorarchives are starting to get interested • The project will grow and evolve • We are starting to discuss the value of the information we calculate • It is not easy, but it can be very interesting • Integration with major SPARQL backends • WikiData, DBPedia, ...
- 24. Semantic technologies •Estabilshed as high end complex infrastructure • Data integration in (illuminated) Public Administrations • Where is the end user? • Custom tools • Custom queries • Custom taxonomies
- 25. Culture • Semantictech is the «technological form» of the sharing economy • An endpoint gains value sharing its resource elements and taking shared resource elements • We need to decide where the Commons end and where Private data starts • This decision is probably the most complicated in the world
- 26. Need for developers Need for tools • DBPedia, WikiData can be the starting point • We need to create new tools to leverage semantic data • We need to create new tools to create new semantic data • We need to keep our feet on the ground and remember that Technology is just a pretext for the bigger prize
