I am currently planing and testing Omeka S for building an online cassettography. In fact the idea is to move from MediaWiki to Omega S for this project: https://african-cassettes.uni-mainz.de.
Since a lot of the properties we use in this project are not (yet) included in standard ontologies I have to create a new ontology using the module “Custom ontologies”.
But for some reason I was unable to create a new ontology. My steps are the following:
- I create a new ontology by entering
Namespace uri: https://www.omeka-s.african-cassettes.de/ns/tk7/
Prefix: tk7
Label: testk7
and add a comment;
then I enter a couple of classes and properties I want to create, such as
in the field “Create specific classes”:
testk7:CassetteAlbums
and “Create specific properties”
testk7:trackinglist
testk7:arrangement
testk7:recordingstudio
testk7:label
testk7:labelnumber
testk7:labelplace
testk7:distribution
testk7:distributionnumber
testk7:distributionplace
- When I finally click on “Get turtle” I get an error message "No ontology exists for prefix “testk7"” for every class and property.
What is my mistake? As far as I understand the explanatory text “The next three forms are independant, and can be used together (for a new ontology)” I should be able to create a new ontology by filling all three forms together. But it looks like I’m overlooking something.
A helpful answer is highly appreciated.
