| Data | Description | Suggested example Implementation |
| simal:collected | The date a fact was collected | <collected> YYYY-MM-DD</collected> |
| simal:source | The source of the document | <source> JISC</source> |
Relationship between schemas
For each project that is newly imported into Simal, a new simal:Project is created and a simal:ProjectId is generated. The DOAP file is kept as is and is referenced from the simal:Project via an rdfs:seeAlso. If the imported project has an rdf:about URI this will be used, for the reference, otherwise one will be generated that is specific to the source of the import.
Multiple DOAP files can be imported for the same project. See the figure below:
The same is true for entities of type foaf:Person. A simal:Person is created for a foaf:Person with an rdfs:seeAlso reference to the original foaf:Person. This has no effect on the doap:Project which will still reference to the original foaf:Person.
