[UI] Support using SHACL Shapes for Searching, Querying and Filtering

[edmondchuc]

Other than form rendering of data, SHACL should also support generating forms for searching, querying and filtering.

These search forms can be described using a combination of node shapes, property shapes and their constraints. For example, a simple facet filter can be described using a property shape with sh:in with the possible values. More complex facets with autocomplete can be composed together with a node shape, property shape and label role.

Discussion:

• Confirm the use case
• Can this be reused outside of user-interfaces?
