Description

This ontology provides an extension for document types for the ISO 21597 ICDD Part 1 Container ontology ct: <https://standards.iso.org/iso/21597/-1/ed-1/en/Container#>.

The preferred namespace prefix is exdoc for the namespace IRI https://w3id.org/exdoc.

It includes the PayloadProxy class as a subclass of the ct:ExternalDocument class for registering payload triples from the "payload triples" folder. Instances of these classes can be used to define link elements for RDF-based data in ICDD containers. It also includes the ExternalRelationalDatabase and ExternalInfluxDatabase classes as a subclasses of the ct:ExternalDocument. The ExternalRelationalDatabase class can be used to provide information and connection details from an existing relational database, e.g., to retrieve data from DB and convert it into payload triples using R2RML mappings (see W3C R2RML Recommendation). When working with databases in ICDD container, be sure you do not store credentials for the database in the connection string but in a secure credentials store. The ExternalInfluxDatabase is used to retrieve time-series data from an InfluxDB instance.

* **History Note:**

v0.5: added ExternalInfluxDatabase class

v0.4: added PayloadProxy class

v0.3: added databaseMapping reference

v0.2: added databaseType and databaseQueryLanguage

v0.1: initial ontology

database mapping,

database mapping

Property	Value
IRI	https://w3id.org/exdoc#databaseMapping
