Version History

...

The publicly released version IRI MUST use a numeric version formed with the release year and a monotonically increasing number NN in YYYYNN form, such as 202202 for the second release in 2022. If the IOF releases every quarter, NN represents the quarter when the ontology was released. When a versioned IRI is formed, the version MUST appear before the topic. All IOF ontologies that are part of a release MUST share a common version.

...

The non-versioned IRI MUST always reference the latest released version of the ontology.

• Versioned IRI: https://spec.industrialontologies.org/ontology/202202/supplychain/meta

• Non-Versioned IRI: https://spec.industrialontologies.org/ontology/supplychain/meta

...

A data property MUST be a verb phrase starting with is for boolean (true/false) or has for any other data type. The data property SHOULD end with Value unless it is a boolean.

Examples:

• hasTagValue

• hasDateValue

• isTransferable

...

• Rules MUST be in a subdirectory called addenda under the related ontology directory in the IRI.

  • Examples:

    • /ontology/core/addenda/swrl/CoreRules

    • /ontology/core/temporal/addenda/swrl/AllensTemporalRules

    • /ontology/core/addenda/shacl/CoreShapes

    • /ontology/core/addenda/propertychain/CorePropertyChains

• The following naming rules MUST be used for the following artifacts:

  • .../addenda/swrl/ : the directory swrl MUST be used for all SWRL (Semantic Web Rule Language) files

  • .../addenda/shacl/ : the directory shacl MUST be used for all SHACL (Shape Constraint Language) files

  • .../propertychain/ : the directory propertychain MUST be used for all files containing property chains

SWRL IRIs

SWRL ontologies have the following requirements for the ontology and their parts. The IRI MUST conform with the Ontology WG meeting.

SWRL Variables

Examples:

• /ontology/core/temporal/addenda/swrl/AllensTemporalRules/firstInterval1
