Sources

Overview

The API exposes a representation of sources which are versioned repositories of concepts (or codes, terms, measures, metadata definitions) and mappings. A Source is used to create and edit concepts and mappings, whereas a Collection is used to build a set of concepts and mappings from one or more sources. A Source can be used to build a FHIR CodeSystem or a FHIR ConceptMap – see OCL FHIR Overview for more information.

Examples of a Source include an OpenMRS concept dictionary (e.g. CIEL, AMPATH, PIH), a reference terminology or codeset (e.g. SNOMED CT, ICD-10), or indicator registry (e.g. WHO Indicator Registry). Custom dictionaries are also supported, which are useful for representing local or proprietary content or content that is still under development. A Source is owned by either a user or an organization.

OCL supports “internal” and “external” sources. An internal source is one whose concepts and mappings are being managed on OCL. Its metadata as well as concepts, classes, datatypes, mappings, maptypes, etc. may all be edited by a user with sufficient privileges. An external source acts as placeholder for mappings to concepts that are not stored in OCL. For example, the SNOMED CT terminology is not hosted on OCL, but the IHTSDO organization and SNOMED CT source do exist as a placeholder to map to SNOMED CT terms.

Example uses:

GET /orgs/WHO/sources/ICD-10-2010/ - Get an organization’s source
GET /users/johndoe/sources/my-source/ - Get a user’s source
GET /user/sources/my-source/ - Get the authenticated user’s source

Versioning of sources

The current state of a source’s metadata and all of its resources is referred to as its HEAD. All changes to a source’s metadata and resources are made to the HEAD of the source, and prior source versions are not affected. The source HEAD is used when no source version is otherwise specified in a request. For example, GET /user/sources/MySource/HEAD/ and GET /user/sources/MySource/ will retrieve the HEAD source version, whereas GET /user/sources/MySource/v1.0/ will retrieve the source version with an ID of “v1.0”.
Versions of a source are a frozen pointer to the state of the source’s concepts, mappings, and metadata at a specific point in time, similar to “tags” in GitHub. The “frozen” data includes the source metadata (name, descriptions, etc.).
Source versions can be marked as “released” or “retired” to indicate to users how the contents of a source version are intended to be used. Any number of source versions may be marked as “released”.
The latest source version is a magic keyword that automatically refers to the most recent released version of a source, e.g. GET /user/sources/MySource/latest/

Managing user permissions to a source

The public’s access to a Source may be set to Edit, View or None. Typically sources are marked as View, which allows any authenticated user to view the content of the source but only users with additional permissions may edit the source. If a source is marked as Edit, then any authenticated OCL user may make changes to it, so this should be used only in rare situations. A private source is one that is marked as None– only user’s with explicitly shared access may search or perform actions on the concepts in a private source.

Get a single source

Get a public source owned by an oragnization or user

GET /users/:user/sources/:source/
GET /orgs/:org/sources/:source/
GET /user/sources/:source/

Parameters (only applicable when including child concepts or mappings in the response)
- includeConcepts (optional) boolean - set to true to include the concepts owned by this source in a child attribute named concepts
- includeMappings (optional) boolean - set to true to include the mappings owned by this source in a child attribute named mappings
- offset (optional) integer - zero-based index of the concepts and mappings to return; default is 0; note that this is only applicable if includeConcepts or includeMappings is set to true
- updatedSince (optional) datetime - ISO 8601 timestamp (e.g. 2011-11-16T14:26:15Z) that filters the returned concepts and mappings to only those updated after the specified date/time; note that this is only applicable if includeConcepts or includeMappings is set to true
- includeRetired (optional) boolean - set to true to include retired mappings or concepts in the response; note that this is only applicable if includeConcepts or includeMappings is set to true
- limit (optional) numeric - set to the maximum number of concepts and mappings to return with the source; note that this is only applicable if includeConcepts or includeMappings is set to true

Response

Deactivate a source

Deactivate the specified source owned by the authenticated user

DELETE /user/sources/:source/
DELETE /orgs/:org/sources/:source/

Notes
- This only deactivates the source using an internal flag. This effectively hides the source and any data or metadata it contains from OCL. Note that this may not necessarily delete the contents from the system.
- Authentication information for a user with administrative access to the source must be passed with the request. E.g. curl -u "username" "/users/johndoe/"

Response

Status: 204 No Content

Get single version of a source

Get a single version of a source, where :version is “latest” or a source version ID

GET /user/sources/:source/:version/
