Linked Data Tools and Workflows



At Linked Pasts IV in Mainz 2018, the Linked Pasts Network had a Session on "Parallel Breakous with Buffet Lunch", chaired by Leif Isaksen and Valeria Vitale (Pelagios Commons). Table 1 discussed about Tools and Pipelines. As a result, the #LinkedPipes were born and can be feeded / asked by the following web applications:

How to contribute?

The Linked Pipes semantic modelling is based on the RSE Tools Ontology, which is available as OWL file via the Research Squirrel Engineers. The ontology assumes that a tool is linked into the Linked Open Data Cloud via Wikidata. The tools must be an instance of a Little Minion. Please follow the next steps to create your Little Minion, aka Linked Tool and Linked Pipe.


  1. Create a Wikidata account.
  2. Login on Wikidata.
  3. Create a new Item on Wikidata, language: en, label: tool name, description: short description.
  4. Describe your item (linked tool).
  5. It is recommended to tag instances like Q193424 (web service), Q312466 (utility software), Q7397 (software) or Q184148 (plug-in).
  6. It is recommended to tag genres (P136), developes (P178), a git source code repository (P1324), official website (P856), etc.
  7. Examples: Alligator or SPARQLing Unicorn QGIS Plugin
  8. After that process, keep the Q... identifier in mind.

turtlenator / GitHub

  1. Open the turtlenator.
  2. Create a Linked Tool or Linked Pipe and copy the turtle fragment.
  3. Create a Github account or login.
  4. Open the linkedpipes.ttl source file, edit it, copy the turtle fragment (without the prefixes) into the file and send a pull request.
  5. If the request will get accepted, you can see your Tool or Pipe in the toolinator or pipinator.
