# Data models by GTT Project

> Data models: JSON Schemas (2020-12), JSON-LD @context files and RDFS vocabularies. Exact versions (v1.0.0) never change; major aliases (v1) follow the latest compatible version.

Machine-readable list of every model with all its URLs: https://models.gtt-project.org/catalog.json.

## Subject: redmine (Redmine), version 0.1.0

Redmine issues as NGSI-LD entities: datamodels.jp's Task with the terms that Redmine adds, as the GTT project's plugin redmine_gtt_fiware sends them.

- [@context](https://models.gtt-project.org/context/redmine/v0.jsonld): use this alias in data; exact version https://models.gtt-project.org/context/redmine/v0.1.0.jsonld
- [Vocabulary](https://models.gtt-project.org/vocab/redmine/v0.1.0.jsonld): RDFS classes and properties, with labels
- [Task](https://models.gtt-project.org/models/redmine/Task/) (entity type, experimental): A tracked unit of work: a ticket or issue in a tracker, a calendar to-do, a municipal work order. State and priority follow RFC 8984 (JSCalendar); the source system's own status name and kind are kept in statusLabel and subtype. Location may be any geometry. JSON Schema: https://models.gtt-project.org/schema/redmine/Task/v0.1.0.json
