Hi,
I am just starting to explore callimachus.

The use I have in mind is group editing of SKOS data. I have a SKOS file created with the protege SKOS plugin. I can import this as an RDF graph. however it does not show up in the Concept Scheme list. How can I get to use the callimachus SKOS editor on an existing SKOS source?

Hi Andy,

Callimachus can be a great way to collaboratively manage your Linked
Data. Glad to hear you want to give it a try. The SKOS editor in
Callimachus is designed to assist Web application development. It is
there to allow applications to manage small to large categories that can
be used to organize other resources. The goal of the editor is not for
general purpose SKOS editing.

The Callimachus SKOS editor is not used to view all skos concepts. Links
to external concepts go to external websites and should be
viewed/annotated/edited using external means. This allows Callimachus
applications to take advantage of interfaces to large Link Data schemes
(such as LCSH). LCSH provides a good search service that would not be
easily replicated. For this reason the Callimachus SKOS editor only
works for schemes/concepts that were created locally.

Furthermore, to simplify testing, coding, and the user experience the
URIs of concepts are local to the Callimachus HTTP authority and follow
a particular pattern (origin + '/scheme/' + scheme label + '/' + concept
prefLabel).

If you want to use the existing Callimachus SKOS editor (and we welcome
you to do so) you either have to use the interface to (re)create all
schemes/concepts, or you have to migrate your data to be the same as if
it was created by the interface. To migrate your data you have to use a
local (or relative path) URI with the path prefix '/scheme/' and ensure
all the concept URIs start with the scheme URI + '/' and contain no '#'.
You also have to add extra rdf:type </callimachus/skos/ConceptScheme> to
the scheme and </callimachus/skos/Concept> to every concept.

Is your scheme currently in active use? What URI pattern do the concepts
have? How many concepts are there? Are all labels in English? Do you use
complex label resources? Do you have any skos collections or mappings?
