The list below documents the NCBO Web services. For questions on how to use these Web services or to request features, contact Support.

The prefix for all production service URLs in the table below is http://rest.bioontology.org/

Note: All NCBO REST Web services will be required to contain the parameter "apikey=YourApiKey" starting June 2011. The parameter will be added to all Web service calls for the April 27, 2011 release but will not be required until June 2011. To obtain an API key, login to BioPortal and go to "Account" where your API key will be displayed. The addition of the API key replaces the use of the email parameter.

Note: Signatures for BioPortal services have changed in BioPortal 2.0.4 release on January 13th, 2009. This page has the new service URLs.

Signature: ./groups?email={email_address}
Example: http://rest.bioontology.org/bioportal/groups

Services to access ontology views and ontology view versions

Since all the views on ontologies are ontologies themselves all the services that work on ontologies do work for ontology views also with the same signature.

For example to get a specific ontology view based on a version id would be possible by using the signature:

./ontologies/download/{view version id}?apikey={YourAPIKey}

or for getting all view versions of a virtual view can be achieved called using the signature:

./ontologies/versions/{view id}?apikey={YourAPIKey}

However, there are a couple of services that are special for views:

List all the latest version of views

NOTE: To be released in BioPortal version 2.2

Signature: ./views?apikey={YourAPIKey}
Example: http://rest.bioontology.org/bioportal/views?apikey=YourAPIKey

Get all versions of views from a virtual ontology id

NOTE: To be released in BioPortal version 2.2

Description: Returns all versions of views defined on the latest version a virtual ontology, grouped by virtual view ids.
Signature: ./views/versions/{ontology id}?apikey={YourAPIKey}
Example: http://rest.bioontology.org/bioportal/views/versions/1104?apikey=YourAPIKey

Search services

Search BioPortal

Signature: ./search/{query}[?{optional args}]&apikey={YourAPIKey}
Alt Signature: ./search/?query={uri-encoded query}[&{optional args}]&apikey={YourAPIKey}
Example: http://rest.bioontology.org/bioportal/search/Gene?apikey=YourAPIKey
Optional arguments:
- ontologyids=<ontologyid>,<ontologyid>… - limits the search to specific ontologies (default: all ontologies)
- isexactmatch=[1/0] – match the entire concept name (default: 0)
- includeproperties=[1/0] – include attributes in the search (default: 0)
- pagesize=<pagesize> - the number of results to display in a single request (default: all)
- pagenum=<pagenum> - the page number to display (pages are calculated using <total results>/<pagesize>) (default: 1)
- maxnumhits=<maxnumhits> - the maximum number of top matching results to return (default: 1000)
- subtreerootconceptid=<uri-encoded conceptid> - narrow the search to concepts residing in a sub-tree, where the "subtreerootconceptid" is the root node. This feature requires a SINGLE <ontologyid> passed in using the "onotlogyids" parameter.
- objecttypes=<class,individual,property> - limits the results returned to these types, multitple types can be included in the parameter, e.g. class,individual.
Description:

The search attempts to match both partial and exact queries, giving more weight to exact matches. In single-word searches, the wildcard character (*) is automatically appended to the end of the word. For example, searching for "lun" would return all concepts whose name contains a word that begins with "lun" (i.e. "Lung", "Murine Lunate Bone", "Base of the Lung", etc).

In phrase searches (multiple words), the wildcard character is appended to the end of each word. For example, searching for "cut mela" would return all concepts whose name contains a word starting with "cut", followed by any word that begins with "mela" (i.e. "Cutaneous Melanoma", "Metastatic Non-Cutaneous Melanoma", "Cutaneous Melanoma Clinical TNM Finding", etc).

Term services

(formerly referred to as Concept services)

Get term, including its properties, subclasses, and superclasses

Signature: ./concepts/{ontology version id}/{concept id}?apikey={YourAPIKey}
Alt Signature: ./concepts/{ontology version id}?conceptid={uri-encoded concept id}&apikey={YourAPIKey}
Virtual Signature (always uses most recent version of the ontology): ./virtual/ontology/{ontology virtual id}/{concept id}
Alt Virtual Signature (always uses most recent version of the ontology): ./virtual/ontology/{ontology virtual id}?conceptid={uri-encoded concept id}
- To ensure that the Web service works within your application, use the Alt signature as some ontologies may contain terms where the concept id is a URI.
Optional arguments:
- light=[1/0] - when set to 1, returns the "light" version of XML with only a basic info for the concept and its immediate children
- norelations=[1/0] - when set to 1, returns only the requested term information (id, label, fullid, type, synonyms, definitions) without the "relations" map. This is useful when you need to quickly retrieve just the base information about a term.
Examples:

http://rest.bioontology.org/bioportal/concepts/44103?conceptid=O80-O84.9&apikey=YourAPIKey

http://rest.bioontology.org/bioportal/virtual/ontology/1516?conceptid=O80-O84.9&apikey=YourAPIKey

Get all terms using the specific ontology version id

NOTE: 'Get all terms' service has changed. The new signature and examples are reflected below. See #Changes_to_the_Get_all_terms_service for more information.

Signature: ./concepts/{ontology version id}/all?pagesize={pagesize}&pagenum={pagenum}&email={email_address}
Examples:
- http://rest.bioontology.org/bioportal/concepts/40644/all?pagesize=50&pagenum=1&email=example@example.org
- http://rest.bioontology.org/bioportal/concepts/42431/all?pagesize=50&pagenum=500&email=example@example.org
Arguments:
- pagesize: An integer limiting how many results will be returned on a single page (a 'page' is equivalent to a single call to the REST service)
- pagenum: An integer indicating which page of results to return.

Get all terms using the virtual ontology id

NOTE: 'Get all terms' service has changed. The new signature and examples are reflected below. See #Changes_to_the_Get_all_terms_service for more information.

Signature: ./virtual/ontology/{ontology id}/all?pagesize={pagesize}&pagenum={pagenum}&email={email_address}
Example: http://rest.bioontology.org/bioportal/virtual/ontology/1104/all?&pagesize=50&pagenum=1&email=example@example.org
Arguments:
- pagesize: An integer limiting how many results will be returned on a single page (a 'page' is equivalent to a single call to the REST service)
- pagenum: An integer indicating which page of results to return.

Changes to the Get all terms service

Starting in BioPortal 2.3.1 (released March 15, 2010), the 'Get all terms' service has changed to support speedier and more complete term retrieval. To support this, several changes to the response XML and service signature are being made. Please see the following notes to update your existing applications to support these changes.

Examples: A preview of the new service can be seen on the NCBO staging site:
- http://rest.bioontology.org/bioportal/concepts/40644/all?pagesize=50&pagenum=1
- http://rest.bioontology.org/bioportal/concepts/42431/all?pagesize=50&pagenum=500

Signature
- New parameters: Previously, offset and limit were used to control pagination of results. These parameters have been replaced as follows:
  - pagesize: An integer limiting how many results will be returned on a single page (a 'page' is equivalent to a single call to the REST service)
  - pagenum: An integer indicating which page of results to return.

Response: The structure of the new 'Get all terms' response XML has been brought into line with other BioPortal REST term services. In addition, to assist in paging through result sets, 'page' metadata is provided. A list of classBeans is provided in the classBeanResultList element, which includes each classes' set of relations (examples of relations include SuperClass, SubClass, and rdfs:label). Please see the example below for a full demonstration of the new response.

View Extraction Service

This web service can be used to extract a subtree from an ontology. See View Extraction for usage details.

Instance Services

Get all direct instances for a given term

Signature: ./concepts/instances/{ontlogyVersionId}[?conceptid={uri-encoded concept id}[&{optional args}]&email={email_address}
Optional arguments:
- pagesize=<pagesize> - the number of results to display in a single request (default: all)
- pagenum=<pagenum> - the page number to display (pages are calculated using <total results>/<pagesize>) (default: 1)

Example: http://rest.bioontology.org/bioportal/concepts/instances/38801?conceptid=SubstrateType&pagesize=10&pagenum=1&email=example@example.org
Description: returns all direct instances for a given term.

Hierarchy Services

The Hierarchy Services only work on the latest version of the ontology (the "virtual ontology").

NOTE: To see which ontology versions have been processed for use with the Hierarchy Services, see http://rest.bioontology.org/obs/ontologies for ontologies with STATUS=28.

Get paths to root/leaves from a concept in the latest version of a given ontology

Signature: ./virtual/[rootpath|leafpath]/{ontologyId}/{conceptId}[?email={email_address}&{optional args}]
Example: http://rest.bioontology.org/bioportal/virtual/rootpath/1032/Melanoma?email=example@example.org
Example: http://rest.bioontology.org/bioportal/virtual/leafpath/1032/Melanoma?email=example@example.org
Optional arguments:
- offset=<integer> – results offset (used for pagination)
- limit=<integer> – limits the number of results
- delim=<string> – use a custom delimiter between returned terms. Default is a period (.).
Description: The same as the previous services, but takes an ontology id and returns parents from the latest version of that ontology.

Get siblings of a given concept in the latest version of a given ontology

Signature: ./virtual/siblings/{ontlogyId}/{conceptId}?level=<level>&email={email_address}&[&{optional args}]
Example: http://rest.bioontology.org/bioportal/virtual/siblings/1032/Melanoma?level=1&email=example@example.org
Required arguments:
- level=<integer> - limits results to a given level in the hierarchy
Optional arguments:
- offset=<integer> – results offset (used for pagination)
Description: The same as the previous service, but takes an ontology id and returns parents from the latest version of that ontology.

Bio2RDF Dump Service

This service allows you to output a given ontology from BioPortal in the form of a N3 RDF file conforming to the requirements for integrating into the Bio2RDF collection.

Signature: ./ontology/dump_n3/{ontlogyVersionId}?email={email_address}
Example: http://rest.bioontology.org/bioportal/ontology/dump_n3/40865?email=example@example.org

Annotator Service

The NCBO Annotator is a Web service that can be used to annotate text metadata with biomedical ontology concepts. The concepts are from ontologies in BioPortal and includes the Unified Medical Language System (UMLS) Metathesaurus, OBO Foundry candidate ontologies and many others.

The Annotator can be tested via a Web interface available through BioPortal. For more information on using the Annotator Web service, see: http://bioontology.org/wiki/index.php/Annotator_Web_service.

Resource Index Service

The Resource Index provides a mechanism to search for biomedical data based on ontology concepts. For more information on using the Resource Index service, see http://www.bioontology.org/wiki/index.php/Resource_Index.
