Exploring Omeka S API with examples

Let’s assume the API url is https://myomekas.org/api.

URL = https://myomekas.org/

Get all items of ressource class `foaf:person`

Look up the resource of foaf:person.

e.g. all foaf:

URL + api/resource_classes?vocabulary_prefix=foaf

e.g. specifically look for foaf:Person, beware this is case sensitive! foaf:person will have no results.

URL + api/resource_classes?term=foaf:Person

Look for the o:id value, this is the ressource_id. Then get all items of that ressource_id:

URL + api/items?&resource_class_id=96

Get all items of that have a certain property

e.g. all items that have a bibo:translator

URL + api/items?&property[0][property]=bibo:translator&property[0][type]=ex

Get all items with title prename lastname

URL + api/items?property[0][joiner]=and&property[0][property]=dcterms:title&property[0][type]=eq&property[0][text]=prename%20lastname

All metadata, e.g. dcterms, skos and so on can be queried using the parameter key called property. The documentation is pretty thin, but the gist in this few lines: https://omeka.org/s/docs/developer/api/api_reference/#parameters-for-rdf-resources

All items that contain aids in dcterms:description

URL + api/items?property[0][joiner]=and&property[0][property]=dcterms:title&property[0][type]=in&property[0][text]=aids

Get all items that use a specific resource template

First, get the ID of your desired resource template, e.g. 2.

URL + api/items?resource_template_id=2
