Semantic MediaWiki for Community Driven Data Spaces
Download as PPTX, PDF0 likes124 views
This document discusses using Semantic MediaWiki (SMW) to create a knowledge base for the CAF-Network.eu project. SMW allows adding structured data and semantic annotations to wiki pages. It outlines how SMW can be used to create pages about the Common Assessment Framework (CAF), link them to external vocabularies, and query the data in various formats. Reusing existing public sector vocabularies from the EU is recommended to align the project with linked open data standards.
