Goals of Data Catalog

  • index and describe every dataset produced within Ruisdael Observatory, independently from where it is stored or published
  • discover where each dataset is published/stored (via Property:servedBy which points to Category:DataService instances)
  • identify the contact-point of each dataset, special relevant for unpublished datasets (via Property:contactPoint which points to Category:Foaf:Person instances)

Wiki: collaborative editing content management system

suitable to build and maintain a data catalog

  • anyone with an account can enter and edit content
  • anyone with or without an account the view the content
  • forms and templates guide users' edits
  • semantic properties and categories help organize and describe content in machine-readable ways, allowing for structured queries and dynamic content aggregation
  • edit-history function allows reverting pages' content to previous versions

The software: Mediawiki (MW)

  • Open Source Software
  • Powers all Wikipedia instances and Wikidata
  • Markup language - easily converted to/from Markdown, HTML, ...
  • API
  • ecosystem of extensions: ie Page Forms VisualEditor SMW

The extension: Semantic Mediawiki (SMW)

  • Semantic annotations via property::value pairs and classes (categories)
  • User defined semantic properties, classes (categories), queries, controlled-vocabularies
  • RDF export
