Editor's Notes
- Ad worked for TIN until recently. Writes theatre reviews. Visits theatre performances twice a week. Studied Dutch literature and linguistics. Lukas: library of the University of Amsterdam. Library systems…. We know each other: work, twitter, Haarlem
- Librarian hands book to theatre lover: “here is your play”`. It has … pages, no illustrations. Measures book: it is …cm high. And there is an ISBN. Here I have another one. …… TL: this looks like an instruction manual… Video: http://www.youtube.com/watch?v=fFZatmOFpns Etc.
- Restproducten! Only remainders/residuals/waste products
- This was the tragedy part, now for the comedy. Announce Act 2: the pilot project. New roles/parts: Ad likes to mash about with data Lukas likes to link, but does not know how
- Cool URIs don’t change RDF/XML, N3, Turtle
- Need to know URI syntax? Discover?
- An old fashioned ERD data model. More or less similar to an ontology
- This is an example of a triple, two directions! Two triples in one
- Persistent identifiers (part of URI!) String values Working together (we know each others stuff!)
- Using generated HTML, not underlying MARC fields/subfields
- Array of links to internal Theatre database entities (productions)
- Array of links to internal Theatre database entities (people)
- Production JSON also contains identifier/link to digital objects in separate TIN Objects database
- Looks a lot like our own initial attempt ;-)
- We didn't sue JavaScript to remove 'subtitle' after the ' : ' yet. Working on HTML, not underlying MARC fields/subfields
- For instance VIAF for ‘authors’; Wikipedia/DBPedia, etc.
- All ‘implicit relations’
