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 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 for Application Developers: Application developers will also need to include the apikey parameter on all NCBO Web service calls. This allows us to track usage of our system at the level of an application. 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.

Service Output Formats

JSON output scheduled for mid-December release Currently, BioPortal services allow for two output formats: XML (default) and JSON (currently works only for ontology and concept services).

  • XML: no special parameters required. This is the default REST services output format. It assumes the media type as application/xml.
  • JSON: requires an "Accept" request-header with the following value: application/json.

If both application/xml and application/json media types are present in the Accept header, the output format will be determined based on the higher "q" parameter indicating a relative quality factor of each media type. For more info, please refer to: http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html

NOTE: JSON output is currently not available for Annotator Service.

Services to access ontologies and ontology versions

List all the latest version of ontologies

  • Description: Return a list of ontologies in BioPortal. To get information on Ontology Views, use the "List the latest version of all Views" Web service call.
  • Signature: ./ontologies?apikey={YourAPIKey}
  • Example: http://rest.bioontology.org/bioportal/ontologies?apikey=YourAPIKey
    • NOTE: The element <id> contains the value for the ontology version identifier.

Get a specific ontology based on a version id

Download an ontology file

  • Description: Download the file (.obo, .owl) corresponding to the given ontology version id.
  • Signature: ./ontologies/download/{ontology version id}?email={email_address}
  • Example: http://rest.bioontology.org/bioportal/ontologies/download/39002?apikey=YourAPIKey
  • Note: File downloads can include zip archives. Where multiple files are included in the archive, BioPortal uses the following algorithm to determine the primary file: 1) look for a file named the same as the archive with a different extension (IE .owl instead of .zip) and 2) if no similarly-named file exists, use the first file in the list when sorted alphabetically.

Download the latest ontology file

Get all versions of an ontology from a virtual ontology id

  • Signature: ./ontologies/versions/{ontology id}?apikey={YourAPIKey}
  • Example: http://rest.bioontology.org/bioportal/ontologies/versions/1104?apikey=YourAPIKey
  • Note: File downloads can include zip archives. Where multiple files are included in the archive, BioPortal uses the following algorithm to determine the primary file: 1) look for a file named the same as the archive with a different extension (IE .owl instead of .zip) and 2) if no similarly-named file exists, use the first file in the list when sorted alphabetically.

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.

Download a specific ontology view based on the ontology view version id

  • Signature: ./ontologies/download/{ontology version id}?apikey={YourAPIKey}
  • Example: http://rest.bioontology.org/bioportal/ontologies/download/43072?apikey=YourAPIKey
  • Note: File downloads can include zip archives. Where multiple files are included in the archive, BioPortal uses the following algorithm to determine the primary file: 1) look for a file named the same as the archive with a different extension (IE .owl instead of .zip) and 2) if no similarly-named file exists, use the first file in the list when sorted alphabetically.

Get all view versions of a virtual view


However, there are a few Web services that are distinct for views.

Search services

Search BioPortal

  • Boolean Search Options:
    • () parentheses allow to enclose multiple terms joined by OR
      • Example: "(foo bar)" will expand to "foo* OR bar*"
    • - the minus sign preceding a term indicates NOT
      • Example: "foo bar -baz" will expand to "foo* AND bar* AND NOT baz*"
    • No prefix means MUST (required).
  • 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 and includes the preferred name, term identifier, and synonym properties)
    • 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.
    • includedefinitions={true} - if a search result is a hit for a term, adding this parameter will include the definition in the search result xml. Note: Including the definition results in a slight performance hit.
  • 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).

  • Field Values
    • The '<recordType></recordType>' entries can be: PREFERRED_NAME = "apreferredname", CONCEPT_ID = "bconceptid", SYNONYM = "csynonym", and PROPERTY = "dproperty".
    • The '<objectType></objectType>' entries are concept types, which can be: "class", "property", or "individual".

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.
    • maxnumchildren - an integer that sets threshold on the number of children in the SubClass relation for a term. If a term contains more children than the "maxnumchildren", the SubClass relation returns an empty list. The ChildCount relation still contains the correct number of children.

Get all root terms for an ontology version id

Get a path between a term and the root

  • Signature: ./path/{ontology_version_id}/?source={concept1_id}&target=root&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.

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}&apikey={YourAPIKey}
  • Example: http://rest.bioontology.org/bioportal/virtual/ontology/1104/all?&pagesize=50&pagenum=1&apikey=YourAPIKey
  • 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.
    • maxnumchildren: An integer that sets threshold on the number of children in the SubClass relation for a term. If a term contains more children than the "maxnumchildren", the SubClass relation returns an empty list. The ChildCount relation still contains the correct number of children.

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.

  • 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.
      • maxnumchildren: An integer that sets threshold on the number of children in the SubClass relation for a term. If a term contains more children than the "maxnumchildren", the SubClass relation returns an empty list. The ChildCount relation still contains the correct number of children.
  • 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.

Hierarchy Services

The Hierarchy Services provide access to pre-computed term hierarchy information via a single web service call. The pre-computed hierarchy data is generated for only one version of an ontology and is periodically updated. Therefore, if using the Hierarchy Web services, it is best to use the form of the call with the virtual ontology id. To get hierarchy information for any version of an ontology, use the Term Web service to traverse the ontology structure.

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

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.

Ontology Recommender

The Ontology Recommender is a Web service that provides information on what ontology is best covered by your text metadata. An in-depth description and links to the Web service documentation and sample clients can be found at: http://www.bioontology.org/wiki/index.php/Ontology_Recommender_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.


RDF Term Service

  • Signature: ./bioportal/rdf/{ontology version id}/?conceptid={concept id}&apikey=YourAPIKey
  • Alt Signature: ./bioportal/virtual/rdf/{ontology id}/?conceptid={concept id}&apikey=YourAPIKey
  • Alt Signature: ./bioportal/virtual/rdf/{ontology id}/?conceptid={concept id},{concept id},...,{concept id}&apikey=YourAPIKey
    • NOTE: To ensure that the Web service works within your application, url-encode the concept id as some ontologies may contain terms where the concept id is a URI.
  • Examples:
  • Required arguments:
    • ontology version id
    • concept id
  • Description: returns a BioPortal concept as RDF/XML ontology snippet. This is a prototype web service, for updates subscribe to bioportal-announce.
    • The RDF dump will use URIs that are based on which format the ontology is in:
      • OWL/RDF(S): preserve original URIs
      • Protégé & RRF: http://purl.bioontology.org/ontology/{ACRONYM}/{ID}
      • OBO: http://purl.obolibrary.org/{IDSPACE}_{LOCALID}
