Introducing v2

After nearly a year of planning and community input, we are thrilled to release a beta version of ROR's first major schema and API update (version 2.0). The v2 beta is available in the dev API environment with base URL https://api.dev.ror.org/v2/organizations and is open to the public for testing through ~~16 Oct 2023~~ 31 October 2023. Before trying it out, please review the information about the v2 schema and API beta below. For instructions on providing feedback, see How can I provide feedback on the v2 beta? below.

❗️
v2 beta available for API and data dump only
Important note! the v2 beta is available for the API and data dump only. v2 is not yet available for testing in the ROR search interface or ROR reconciler.

About ROR schema & API versioning

In 2022, ROR gathered community feedback and adopted a versioning policy that allows making changes to the schema and API in a way that provides API users with ample time and notice to update to the new schema/API version. Key highlights of this policy include:

Breaking changes to either the schema or API (ex: change to the structure of a field) will be implemented using a new major API version. Minor (non-breaking) changes (ex: a new value allowed for a field whose values comes from a controlled list) will be implemented within the current major API version.
The API version will be supplied in the path portion of an API request, e.g. https://api.dev.ror.org/v2/organizations
Requests that do not include a version in the path portion will be redirected to a default version
2 major API versions will be supported concurrently (the current major version and the most recent previous version).
At least 1 year notice will be provided before sunsetting a major version, via typical ROR communication channels such as our email list, Tech Support Forum, support site, Slack and community meetings.

📘
v2 production release & v1 sunset schedule
Per this policy, we expect to make API v2 available in production in early 2024. v1 (the current version) will remain the default version until at least early 2025.

Schema v2

During early 2023, ROR gathered 3 rounds of community feedback on a new schema version (v2) to address ongoing issues and community use cases that couldn't be supported in the original ROR schema (which was inherited from GRID). Key documents from that process are:

ROR Schema v2.0 draft proposal - proposal open for comment through February 2023
ROR Schema v2.0 second draft proposal - proposal open for comment through April 2023
ROR Schema v2.0 final proposal - proposal adopted April 2023

Key changes in schema v2

Name information previously in name, acronyms, aliases, and labels fields is now contained in 1 parent field, names with subfields lang, value and types. Please note that the lang subfield has only been populated for names with labels in their types. The curation team will be working on adding language codes to other names types over the coming months.
Location information previously in addresses field is now in locations field with subfields geonames_id and geoneames_details. Many fields containing very granular information derived from Geonames have been removed, as this information is avilable directly from Geonames. Additionally, country code and name information previously in the country field has been moved to locations.geonames_details.country_code and locations.geonames_details.country_name
Website/domain information previously in links and wikipedia_url have been combined into a 1 parent field links with subfields type and value. The ip_addresses field has been removed (it was not populated by GRID for any records). The domains field has been added, however, please note that this field has not yet been populated. The curation team will be working on this over the coming months.
External identifiers information has been restructured within the existing external_ids field. Each item in external_ids now has subfields type, all and preferred. The data type for all is a list for each external_ids item, whereas it was previously a string for GRID IDs and a list for other ID types.
Administrative information was not included previously. A new parent field admin has been added, which contains subfields created and last_modified. Each of those subfields contains additional subfields date and schema_version. Created date for each record was extracted from previous GRID and ROR releases. Last modified dates were extracted from ROR releases only, as, at a minimum, each record in ROR has been modified by the ROR curation team to add a ROR ID in the id field.
Controlled lists previously had variations in casing. For example, values in the types and relationships.type fields began with an uppercase character, while values in status were lowercase and external ID types contained a variety of casings. In v2, allowed values in controlled lists are consistently lowercase, with the exception of country codes derived from ISO-3166, which are uppercase per the standard.

For details and examples of each field, see the Schema 2.0 doc. You can also view the v2 JSON schema doc in GitHub. For comparison, the current (v1) JSON schema doc is also available in GitHub. Note that there is additional validation applied to each record beyond the rules specified in the JSON Schema doc, because some rules cannot be expressed in JSON schema (ex: types of relationships allowed between active and inactive records).

API v2

The v2 REST API includes all the same search and retrieval functionality as the current (v1) REST API, but with ROR records in responses formatted according to the v2 schema.

❗️
v2 API currently available in dev environment only
During this beta period, the v2 API is only available in the ROR dev environment at https://api.dev.ror.org/v2/organizations.

Specifying the API version

For all ROR API requests, the API version is specified in the path portion of the request, ex

curl https://api.dev.ror.org/v2/organizations

Version options available during this beta test are:

v1 https://api.dev.ror.org/v1/organizations Returns a response formatted using the original ROR data model (which was not versioned when introduced, but it being retroactively versioned as v1.0)
v2 https://api.dev.ror.org/v2/organizations Returns a response formatted using the v2.0 ROR data model
No versionhttps://api.dev.ror.org/organizationsReturns a response formatted using the default version, which is currently v1. Same response as v1 https://api.dev.ror.org/v1/organizations. After the production launch of v2 (planned for Jan 2024), the default version will remain v1 until approximately Jan 2025, when the default version will be changed to v2.

Example API requests

Retrieve a single ROR record

As in the current production API, the ROR ID included in this request can be formatted like 00tjv0s33, ror.org/00tjv0s33 or https://ror.org/00tjv0s33.

curl 'https://api.dev.ror.org/v2/organizations/00tjv0s33'

Retrieve list of ROR records

curl 'https://api.dev.ror.org/v2/organizations'

Query parameter search

curl 'https://api.dev.ror.org/v2/organizations?query=Bath'

Advanced query parameter search

The biggest difference in API v1 vs v2 is the fields available to search using ?query.advanced, because some field names and structures have been added, changed or removed. See the full list of schema v2 fields and subfields below that you can use in advanced queries.

Search a single field

curl 'https://api.dev.ror.org/v2/organizations?query.advanced=names.value:%22Harvard%20University%22'

Search multiple fields

curl 'https://api.dev.ror.org/v2/organizations?query.advanced=names.value:Cornell+AND+locations.geonames_details.name:Ithaca'

Search by last modified date for records modified between 2 dates (using a range query). Note that unescaped reserved characters such as [, ], {, and } must be used in range queries. This is the use case they are reserved for! Escaped brackets and braces will be processed as string literals and will not produce the expected results.

curl 'https://api.dev.ror.org/v2/organizations?query.advanced=admin.last_modified.date:[2023-07-01%20TO%202023-09-05]'

Search by created date for active records created before a specific date (using a range query).

curl 'https://api.dev.ror.org/v2/organizations?query.advanced=admin.created.date:{*%20TO%202019-12-31}'

Affiliation parameter search

curl 'https://api.ror.org/v2/organizations?affiliation=UCL%20School%20of%20Slavonic%20and%20East%20European%20Studies'

Paging & filtering

As in the current API, results for /organizations, ?query and query.advanced requests with more than 20 results are paginated, with the first 20 results returned by default. A maximum of 10,000 records can be returned with any given request. ?affiliation requests are not paginated. For more information, see Paging.

As in the current API, results for /organizations, ?query and query.advanced can be filtered by status, type, country code and country name. ?affiliation requests cannot be filtered. For more information, see Filtering. When filtering by country name/code in v2, the following filter names are equivalent and can be used interchangeably:

country.country_code and locations.geonames_details.country_code
country.country_name and locations.geonames_details.country_name

Formatting search strings (special characters, wildcards, etc)

As in the current API, all search strings used ?query, ?query.advancedand?affiliation requests must be URL-encoded and Elasticsearch reserved characters must be escaped. Elasticsearch query string syntax is supported for ?query and ?query.advanced requests, but not for ?affiliation requests. For more information, see Formatting searches.

Record status

As in the current API, all requests except requests for a specific ROR record (by its ID) return only records with a status of active by default. Records with a status of inactive or withdrawn can be included in results by adding an additional parameter all_status to your request. This parameter can be used in combination with the ?query, ?query.advanced or ?affiliation parameter. For more information, see Retrieve a list of records with all statuses.

Data dump v2

Sample data dumps containing both v1 and v2 files are available on GitHub at <https://github.com/ror-community/ror-data-test>. Updated v2 samples are added with every new ROR release.

🚧
The files in https://github.com/ror-community/ror-data-test are for testing only and are not official release files.

The sample zip files provided each contain 4 files: 2 files with data using schema v2 (JSON and CSV) and 2 files using schema v1, as in the examples below:

v1.33-2023-09-21-ror-data_schema_v2.json (new file not in production data dumps - JSON data dump with records in v2 schema)
v1.33-2023-09-21-ror-data_schema_v2.csv (new file not in production data dumps - CSV data dump containing a subset of v2 fields)
v1.33-2023-09-21-ror-data.json (JSON data dump with records in v1 schema)
v1.33-2023-09-21-ror-data.csv (CSV data dump containing a subset of v1 fields)

📘
Data dump filenames
For individual files inside the vX.XX-YYY-MM-DD-ror-data.zip data dump file:

We will leave the v1 file names as is during the period when v1 is the default version (approx Jan 2024-Dec 2025), in order to allow data dump users time to update their code

Once v2 becomes the default version, v1 data dumps will continue to be produced, however, _schema_v1 will be added to the end of v1 JSON and CSV data dump filenames.

Testing guidelines

As a community-driven initiative, ROR relies on input from its stakeholders to ensure that new and updated features serve the needs of its wide array of users and use cases. We invite the ROR community to test and provide feedback on schema and API v2 through ~~16 Oct 2023~~ 31 October 2023. During this beta period, the v2 API is only available in the ROR dev environment at https://api.dev.ror.org/v2/organizations.

Who should participate in the ROR schema & API v2 beta?

This beta is open to the public, and all feedback is welcome. We're particularly seeking feedback from current and prospective ROR API and data dump users, especially those with a technical focus who work directly with ROR data through software development, product design/specification, support, etc.

What kind of feedback is ROR looking for in this beta?

This beta is focused on functionality of the v2 schema and API (rather than the data contained in the records - see note on v2 data below). Examples of feedback we're most interested in are:

Bugs specifically related to v2, ex: a request that works as expected in the current API, but does not work as expected when repeating the same request in the v2 API.
Use case issues related specifically to schema/API v2, ex: a ROR API or data dump feature/functionality that you use right now is not available in v2, or an aspect of the v2 API or data dump will present major implementation challenges for your use case.
Other comments/feedback specifically related to the v2 schema, API and/or data dump

What kind of feedback is not in scope for this beta?

Major changes to schema v2. During early 2023, we conducted 3 rounds of public comment on v2 of the schema, and through that process, many current/prospective ROR users helped to shape the resulting v2 schema. To request a change for consideration in a future schema version, please submit a schema change request.
Feedback related to the ROR search interface, which is not included in this beta.
General bug reports or feature requests that are not related specifically to v2. Please submit general bug reports and feature requests separately.
Requests for updates/additions to records in the ROR registry. To request an update or addition to ROR, please use the curation request form.

Important notes about v2 record data

There are several new fields/subfields in v2, and the dataset used in the beta has not been fully updated with values in all new fields/subfields. In particular:

Created/last modified dates HAVE been added to all records, using actual dates from GRID and ROR data releases.
Domains HAVE NOT been added. This field is currently an empty list for all records. This field requires careful curation to ensure accuracy. We plan to add data to this field over the coming months.
Language codes for items in the names fields are only included for names inherited from the labels field in the current schema. Language codes HAVE NOT been added for names inherited from the name and aliases fields in the current schema. We plan to add language codes over the coming months, with the goal of ensuring that (minimally) each name with “ror_display” in its types has a language code.

How can I provide feedback on the v2 beta?

Check the ROR schema & API v2 beta project board to see if the same or a closely related issue has already been reported. If so, please add comments to that issue.
If you have new feedback that’s not related to another issue on the ROR schema & API v2 beta project board, submit a Github issue using the ROR schema & API v2 beta feedback template.

All issues will be reviewed by ROR staff, and they may contact you using your Github handle to request additional information. If you are not a Github user or prefer to submit your feedback privately, please email [email protected] . Please provide your feedback by ~~16 Oct 2023~~ 31 October 2023.**

Testing tips

Not sure where to start? We recommend testing v2 based on the ROR feature(s)/functionality you're using now. If you're not sure which features are available in the the current production environment, see the ROR REST API and data dump documentation.

API users

Determine which request(s) your applications/services are currently making to the ROR API. Test those requests using the v2 dev API, with base URL <https://api.dev.ror.org/v2/organizations> .
Review the v2 result(s) and the response format to v1. Note that since v2 uses a separate Elasticsearch index from v1, and since v2 records contain different data from v1, there may be small variations in the number and order of results returned.
Submit feedback about any bugs encountered and/or any aspects of the v2 API/schema that will present significant implementation challenges for you/your use cases, per How can I provide feedback on the v2 beta?

Data dump users

Download and review a sample v2 data dump from https://github.com/ror-community/ror-data-test.
Check whether you are able to extract and work with records in the v2 files as needed for your ROR use case.
If you use both the JSON data and the CSV data in the data dump, be sure to test whether you are able to work with both files.
Submit feedback about any bugs encountered and/or any aspects of the v2 data dump that will present significant implementation challenges for you/your use case, per How can I provide feedback on the v2 beta?

We are grateful for your help! Following the close of the beta test on ~~October 16, 2023~~ October 31, 2023, we will review all reports and work to incorporate the improvements before we release v2 into production.
