Editing ontologies:

'#' vs. '/' URIs

There has been an ongoing debate about '#' vs. '/' . We focus on ontologies with '#' here with URIs like: http://persistence.uni-leipzig.org/nlp2rdf/ontologies/nif-core#String Note that ontologies with '/' URIs need to published differently (partly discussed here: http://lists.w3.org/Archives/Public/semantic-web/2013Apr/0157.html).

Workflow for '#' ontologies in this repository

  1. All ontologies are edited in Turtle syntax with the Geany text editor or any other Turtle editor ( e.g. http://aksw.org/Projects/Xturtle.html), and include developers' comments using "#" directly in the source, see e.g. nif-core/nif-core.ttl
  2. A script called publish.sh does the following:
  1. Then we use git to commit and push the changes to GitHub
  2. see the .htaccess for redirect rules
