djangoldp-tamis 2.0.0

djangoldp package for TAMIS

# DjangoLDP TAMIS

Django/[DjangoLDP](https://git.startinblox.com/djangoldp-packages/djangoldp) package that provides the backend data model for TAMIS, a workflow tool for audiovisual post-production. It exposes the domain as Linked Data Platform (LDP) resources so it can be consumed by the matching web-components package [solid-tamis](https://git.startinblox.com/components/solid-tamis).

## Functional overview

TAMIS coordinates post-production work between a Client (who orders content finishing) and a Provider (who performs it) — typically subtitling, dubbing, mix, conform, color, etc. Work is tracked against the broadcaster-style editorial hierarchy Serie → Season → Programme → EditorialWork, with standalone movies sitting directly as a Programme (no series); both shapes are first-class.

The unit of work is a `Prestation` — one contracted job attached to an EditorialWork. Prestations are grouped under a `Commande` (a purchase order between a specific Client and Provider) and cross-referenced to external systems via `Identifiant`s (issuer Agent + identifier string), which is how a TAMIS EditorialWork maps to a broadcaster’s asset ID.

Every prestation carries an ordered timeline of `Step`s built from a template. Three steps are seeded at app startup — Refusé, Validation, Livraison — and the workflow is enforced by signals:

• the last two steps of any prestation are always Livraison (delivery) → Validation (client sign-off);

• adding a Refusé step (rejection) automatically re-queues Livraison + Validation after it, so a rejection cleanly restarts the delivery → validation loop without the operator having to rebuild the timeline;

• step ordering is renumbered after every change so the UI can render a stable sequence.

Each prestation produces deliverables: an empty Asset is auto-created on prestation creation; assets hold MediaResource`s (the actual file: name, size, `Format), broken down into Track / AudioTrack / VideoTrack. EditorialWork.assets is a computed rollup of every asset across the editorial work’s prestations — the “all deliverables for this episode/film” view.

Access is team-based, not ownership-based. Every prestation owns three Django groups — admins / editors / visitors — wired to ACLPermissions. The same prestation can therefore have the client’s QA reviewers as visitors, the provider’s operators as editors, and a studio lead as admin. TamisProfile carries enterprise/title/job/phone so the UI can show who’s who across organisations, and Favourite lets users pin prestations for quick access.

## What it provides

A Django app (djangoldp_tamis) that models the editorial hierarchy and the delivery workflow around it:

• Editorial hierarchy — Serie → Season → Programme → EditorialWork, typed against the [EBUCore Plus](http://www.ebu.ch/metadata/ontologies/ebucoreplus) ontology (ec:Programme, ec:EditorialObject, …).

• Prestations — a Prestation is a unit of work attached to an EditorialWork, with a template-driven ordered list of Step`s (`StepToTemplate → PrestationStep). Three seeded steps — Refusé, Validation, Livraison — are created automatically on app startup and their order is maintained by signals (a rejection re-appends Livraison + Validation; the last two steps are always guaranteed).

• Per-prestation access control — each Prestation owns three Django Group`s (`admins, editors, visitors) wired to ACLPermissions, so team membership (not object ownership) drives who can view/change/control a prestation. Memberships are exposed on LDPUser.prestations as a dynamic nested container.

• Commandes — Commande groups prestations under a Client/Provider pair, with free-form Identifiant`s (issuer `Agent + identifier string).

• Assets & media — Asset (inherits prestation permissions) → MediaResource → Track / AudioTrack / VideoTrack, with Format lookup. EditorialWork.assets is a computed nested container aggregating all assets across its prestations.

• Profile — TamisProfile (one-to-one with the user), auto-created on user save.

• Admin — registers all public models under DjangoLDPAdmin with inlines for prestation steps, assets, and media tracks; replaces the default Group admin with a read-only variant.
