RELATIONALDATABASE

What is a metrical repertoire?

• Gaston Raynaud, Bibliographie des chansonniers francais des XIIIe et XIVe siecles, 1884.

• Gotthold Naetebus, Die nicht lyrischen Strophenformen des Altfranzosischen, 1891.

• Pillet & Carstens, Bibliographie des Troubadours, 1933

Print repertoires

Linking repertoires…

• 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

Interoperability & TEI

Linking Data ChallengeThe Linked Data Challenge

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

ReMetCa’s Ontology

Available at: http://www.purl.org/net/remetca and http://datahub.io/dataset/remetca-ontology

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
