RDF Schemas
Adding metadata and using it from a program works…
… provided the program
knows
what terms to use!
We used terms like:
Chart
,
LabelledBy
,
IsAnchor
, ...
ChartType
,
GraphicsType
, ...
etc
Are they all known? Are they all correct?
It is a bit like defining record types for a database
This is where RDF Schemas come in
officially: “RDF Vocabulary Description Language”
gives the fundamentals for general ontologies
