2. Cubiss DataSpace Deel 1: Wat is de Cubiss DataSpace? Deel 2:
Hoe werkt het? Deel 3: Wat kun je ermee?
3. Cubiss DataSpace: Wat is het? RDF DBMS (triplestore) SPARQL
endpoint HTTP URI resolving (Linked Open) Data
4. Cubiss DataSpace: Wat is het? Virtuoso Open Source (triple
store): Virtuoso Universal Server is a middleware and database
engine hybrid that combines the functionality of a traditional
RDBMS, ORDBMS, virtual database, RDF, XML, free-text, web
application server and file server functionality in a single
system.
5. Cubiss DataSpace: Wat is het? Virtuoso Open Source: SPARQL
endpoint (http://data.cubiss.nl/sparql) Conductor
(http://data.cubiss.nl/conductor) Facetted Browser
(http://data.cubiss.nl/fct)
6. Cubiss DataSpace: Wat is het? HTTP URI resolving: Internet =
TCP/IP,HTTP,FTP,SMTP,URL,etc... Hyper Text Transfer Protocol: The
Hypertext Transfer Protocol (HTTP) is an application protocol for
distributed, collaborative, hypermedia information systems. HTTP is
the foundation of data communication for the World Wide Web.
7. Cubiss DataSpace: Wat is het? URI = Uniform Resource
Identifier URL == URI maar URI =/= URL IRI == URI maar URI =/= IRI
IRI URI URL
8. Cubiss DataSpace: Wat is het? Content negotiation: Content
negotiation is a mechanism defined in the HTTP specification that
makes it possible to serve different versions of a document (or
more generally, a resource representation) at the same URI, so that
user agents can specify which version fit their capabilities the
best.
9. Cubiss DataSpace: Wat is het? Linked Open Data = RDF data +
eisen: make your stuff available on the Web (whatever format) under
an open license make it available as structured data (e.g., Excel
instead of image scan of a table) use non-proprietary formats
(e.g., CSV instead of Excel) use URIs to denote things, so that
people can point at your stuff link your data to other data to
provide context
10. Cubiss DataSpace: Wat is het? RDF data = triples
11. Cubiss DataSpace: Hoe werkt het? De LOD cyclus:
12. Cubiss DataSpace: Hoe werkt het? Management van data:
Graphs (logische clusters) Data Metadata (ontologie) Data
kwaliteitsbewaking
13. Cubiss DataSpace: Hoe werkt het? Data authoring (bewerken)
OntoWiki; OntoWiki facilitates the visual presentation of a
knowledge base as an information map, with different views on
instance data. It enables intuitive authoring of semantic content,
with an inline editing mode for editing RDF content, similar to
WYSIWIG for text documents.
15. Cubiss DataSpace: Hoe werkt het? Links: Over relaties
tussen data... ;) Ontology Authorities Graphs (domain)
Resources
16. Cubiss DataSpace: Hoe werkt het? Links: Matchen van
concepten in verschillende datasets. Bijvoorbeeld SILK Bijvoorbeeld
GATE Basis benodigdheden: RDF en SPARQL
