Custom Ontology (module for Omeka S)

====================================



> __New versions of this module and support for Omeka S version 3.0 and above

> are available on [GitLab], which seems to respect users and privacy better

> than the previous repository.__



[Custom Ontology] is a module for [Omeka S] that allows to create specific

classes and properties to describe resources when no standard ontologies are

available, in particular on [LOV], [schema.org], [W3C], and in many other

places. It is useful to manage internal properties, or for researchers who are

creating new data. The properties and classes are available via the standard api

of Omeka S too, like any other ontology.



In fact, this module is a replacement of an existing feature on [Omeka Classic],

where it was allowed to edit and create [item types], equivalent of resource

classes and resource templates, and to create new elements, equivalent of

properties. In Omeka S, in order to share data and to follow the standards of

the semantic web, this feature was not ported.



Note that it is always recommended to search and use existing ontologies first,

because it will be simpler to share data and to link them semantically. If the

properties are known only by you and are not described anywhere, it will be hard

to match them and to make relations with other.



This module avoids to create a specific rdf vocabularies, turtle or n3 files

too, so anybody can use Omeka S like wished, with any documents or resources.



Installation

------------



See general end user documentation for [installing a module].



Download the last release [CustomOntology.zip] from the list of releases,

uncompress it in the `modules` directory and rename module folder `CustomOntology`.

Then install it like any other Omeka module and follow the config instructions.



This module has no dependencies.



Usage

-----



The module adds a button in the header of the vocabulary page and a direct

access in the left sidebar.



Simply click on it and create your ontology, your resources classes or your

properties following the instructions.



Once the form is filled, import it directly via the `Submit` button.



You can add new classes and properties into previously imported ontologies,

but you cannot update existing ones from the form. Nevertheless, you still can

use the turtle file to upgrade the vocabulary later, like for any other

vocabularies, at the core admin page `admin/vocabulary`.



When the custom ontologies are named as proposed (Omeka url + `/ns/prefix`),

they will be publicly listed at `https://example.org/ns` and available as

turtle and other rdf formats (json-ld, rdf/xml, ntriples, [Notation3]), at their

namespace uri, and as a web page at `https://example.org/ns/{prefix}?format=html`.

Content Negociation is managed anyway, so the content type accepted in the

request will be used if not specified by the url query.



TODO

----



- [ ] Add support of version in namespace url.

- [ ] Add edition of terms and labels directly on the page vocabulary, with a main edit button and some js (see module Folksonomy).



Warning

-------



Use it at your own risk.



It’s always recommended to backup your files and your databases and to check

your archives regularly so you can roll back if needed.



Troubleshooting

---------------



See online issues on the [module issues] page on GitLab.
