OLDAPlib

Basic library for OLDAP Python-based backend. OLDAP relies as much as possible on standard ontologies. Currently, the following ontologies are being used:

• xs: <http://www.w3.org/2001/XMLSchema#>
• rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
• rdfs: <http://www.w3.org/2000/01/rdf-schema#>
• owl: <http://www.w3.org/2002/07/owl#>
• skos: <http://www.w3.org/2004/02/skos/core#>
• sh: <http://www.w3.org/ns/shacl#>

Setup of IRI's and namespaces

The generic base IRI that is to be used has the form of

http://oldap.org/<location>

<location> is a unique name identifying the OLDAP installation of the type NCName.

System namespace

System ontologies and SHACL files

All system relevant definitions like system-wide ontologies or shacl definitions are in a graph named

http://oldap.org/base#

System-wide data

Data such as project information, user data etc. is in a graph named

http://oldap.org/<location>/data#

Project specific graphs

Each project has several namespaces (aka "named graphs")

Project specific data

All project specific data resides in a graph named

http://oldap.org/<location>/<project>/data#

The project name must be unique to the location and is of type NCName.
