Cosmos DB Client for Digital Linguistics (DLx)

Database Model

The DLx database has two containers:

  • data
  • metadata

Data

The data container contains Lexemes and Texts. This container is partitioned by language (partition key /language/id). As such, all items in the data container must have a language property whose value is an object with, minimally, an id property. Each item in the container must also have a "type" of either "Lexeme" or "Text". As an example:

{
  "type": "Lexeme",
  "language": {
    "id": "f8a669d3-131b-44f3-88ab-edaa33604202",
    "name": {
      "eng": "Chitimacha"
    }
  }
}

Metadata

The metadata container contains all other types of database objects. Each item in this container must have a "type" property, which is also its partition key (/type).

Types of Metadata

  • BibliographicSource
  • Language
  • Location
  • Media
  • Person
  • User

Permissions

There are 4 types of permissions:

  • public: Any user may view the resource.
  • viewer: The user may view the resource, even when not public.
  • editor: The user may edit but not delete the resource.
  • admin: The user may edit and delete the resource, or set permissions for it.

Objects which have permissions:

  • Bundle
  • Language
  • Note (public only)
  • Project
  • Status (public only)

Permissions on one resource do not imply certain permissions on another permissioned resource. There is no hierarchy of permissions between Projects and Languages. If a Project is publicly viewable, its languages may not be, and vice versa.

Permissions for other items are determined by their parent item, because they are only ever viewable in the context of that parent item. This may result in, for example, a single Lexeme being viewable using one filter but not another. The user may have permission to view a Project's info but not a Language's info, so the user could view that Lexeme in the context of the Project but not in the context of the Language.

Items which get their permissions from their parent items:

  • Lexeme
  • Person
  • Text

It is up to software implementations to impose any type of consistency of permissions between Languages and Projects.

Releases

Releases are currently manual:

  1. npm version
  2. Push to version control.
  3. Create a GitHub release.
  4. GitHub Actions automatically publishes the release to npm.
