Draw UML from SHACL

This diagram generation utility displays an application profile specified in SHACL in the form of one or more diagrams, using PlantUML. It supports a subset of SHACL constraints. The diagrams generated can be embedded in the documentation generation utility. Detailed documentation is available below.

Finding links between boxes

The diagram generation utility will generate a link between 2 boxes if it finds:

An sh:node reference to another NodeShape
An sh:class reference that is the sh:targetClass of another NodeShape
An sh:class reference that is not the sh:targetClass of another NodeShape (in that case a box will be generated corresponding to the sh:class)
An sh:or containing sh:node or sh:class resolved using the same algorithm as above

Limiting the number of arrows/boxes

When the diagram contains strictly more than 8 boxes, then the number of arrows is reduced with this algorithm: if a property shape refer to a node shape that does not have any property, and only one reference is made to that node shape, then that arrow will not be printed and will be replaced by a property inside the node shape box, with a green circle next to it.
This simplification is applied only to the large global diagram, not to the individual diagrams in each section of the documentation, when they are present.

Customizing NodeShapes

In addition to SHACL constraints, the following properties can be used to customise the output of NodeShapes

Property	Type	Description
`foaf:depiction` + `dcterms:title` + `dcterms:description` + `sh:order`	IRI or blank node	Indicates the IRI of a diagram in which the NodeShape will appear. This allows to split the visual representation in multiple diagrams. If `foaf:depiction` is never used on any NodeShape in the SHACL data, a single diagram will be generated with all the NodeShapes. If `foaf:depiction` is used at least once on a NodeShape, then one diagram will be generated for each value of `foaf:depiction`, and each diagram will include only the NodeShapes that refer to it. Each diagram can be described with `dcterms:title` and `dcterms:description` to indicate its title and description. `sh:order` can be used with an xsd:integer value to control the order of the diagrams. Depending on the output format option, you will get a ZIP file containing all PNGs or SVGs, or an HTML page containing all generated diagrams.
`rdfs:subClassOf`	IRI	`rdfs:subClassOf` links are displayed in bold grey. It implies the NodeShapes are also classes, and it of course implies that the submitted file contains the `rdfs:subClassOf` links.
`https://shacl-play.sparna.fr/ontology#background-color`	xsd:string	Color of the box itself. Values can be a color name, like `"Green"` or an hex code, like `"4456BB"`
`https://shacl-play.sparna.fr/ontology#color`	xsd:string	Color of the text inside the box. Values can be a color name, like `"Green"` or an hex code, like `"4456BB"`

Customizing PropertyShapes

In addition to SHACL constraints, the following properties can be used to customize the appearance of Property Shapes

Property	Type	Description
`sh:order`	xsd:integer	Properties are sorted according to sh:order
`https://shacl-play.sparna.fr/ontology#color`	xsd:string	Color of the property name (inside the box) or arrow link. Values can be a color name, like `"Green"` or an hex code, like `"4456BB"`
`owl:inverseOf` on the IRI indicated on `sh:path`	IRI	If the property indicated in `sh:path` is known to have an inverse, then a single arrow will be printed instead of 2.
`sh:group` + `rdfs:label`	IRI	Groups the property inside a section in the box in the diagram, labelled with its `rdfs:label`. This also has the effect of turning "arrows" into "class attributes", in other words displaying object properties as data properties. This is useful to make the diagram more compact for references to e.g. controlled vocabularies / skos:Concept.
