• Issues to consider– Different structure and level of complexity– Different content and time– Different technological systems• SQL databases• Propietary RDBMS systems• XML tagged text
– Different levels of access
Interoperability – or how to link
repertoires…

Why a linked data model
• Based on metadata added to existing databases• Does not alter the internal structure of each
repertoire• Code is published as linked data available on the
web • Extensible and flexible model
Why a linked data model

Some issues
• No previous ontology on poetry existed• Need of standardization of some fields (eg:
metrical and rhythmical scheme)• Need to create controlled vocabularies to
organize information

LOD principles
Information is available on the Web (any format) under an open license
Information is available as structured data (e.g. Excel instead of an image scan of a table)
Non-proprietary formats are used (e.g. CSV instead of Excel)
URI identification is used so that people can point at individual data
Data is linked to other data to provide context
Berners Lee’s Star rating system
