Generate SHACL shapes from data¤
Python Plugin
This operator is part of a Python Plugin Package. In order to use it, you need to install it, e.g. with cmemc.
A task to generate SHACL node and property shapes from an instance data knowledge graph.
Parameters¤
The knowledge graph containing the instance data to be analyzed for the SHACL shapes generation.
The knowledge graph, the generated shapes will be added to.
The label for the shape catalog graph. If no label is specified for a new shapes graph, a label will be generated. If no label is specified when adding to a shapes graph, the original label will be kept, or, if the existing graph does not have a label, a label will be generated. Only labels with language tag “en” or without language tag are considered.
Add result to the existing graph (add result to graph), overwrite the existing graph with the result (replace existing graph with result), or stop the workflow if the output graph already exists (stop workflow if output graph exists).
Import the output graph into the central shapes catalog
Import the SHACL shapes graph in the CMEM shapes catalog by adding an owl:imports statement to the central CMEM shapes catalog.
If the graph is not imported, the new shapes are not activated and used.
Fetch namespace prefixes from prefix.cc
Fetch the list of namespace prefixes from https://prefix.cc instead of using the local prefix database. If unavailable, fall back to the local database. Prefixes defined in the Corporate Memory project override database prefixes. Enabling this option exposes your IP address to prefix.cc but no other data is shared. If unsure, keep this option disabled. See https://prefix.cc/about.
Provide the list of properties (as IRIs) for which you do not want to create property shapes. Example:
Add information about the plugin and plugin settings to the shapes graph.
