Neuroscience Information Framework (NIF) Dysfunction Ontlogy NIFDYS Public 2,750 0 0 0 OWL 1.5 (December, 2012) 08/05/2013 Fahim Imam Description: This ontology contains the former BIRNLex-Disease, version 1.3.2. -- The BIRN Project lexicon will provide entities for data and database annotation for the BIRN project, covering anatomy, disease, data collection, project management and experimental design. It is built using the organizational framework provided by the foundational Basic Formal Ontology (BFO). It uses an abstract biomedical layer on top of that - OBO-UBO which has been constructed as a proposal to the OBO Foundry. This is meant to support creating a sharable view of core biomedical objects such as biomaterial_entity, and organismal_entity that all biomedical ontologies are likely to need and want to use with the same intended meaning. The BIRNLex biomaterial entities have already been factored to separately maintained ontology - BIRNLexBiomaterialEntity.owl which this BIRNLex-Main.owl file imports. The Ontology of Biomedical Investigation (OBI) is also imported and forms the foundation for the formal description of all experiment-related artifacts. The BIRNLex will serve as the basis for construction of a formal ontology for the multiscale investigation of neurological disease.

Tissue Microarray Ontology TMA Public 7 0 0 0 OWL 1.0.0 05/07/2010 Chuck Borromeo Description: Tissue microarrays (TMA) are enormously useful tools for translational research, but incompatibilities in database systems between various researchers and institutions prevent the efficient sharing of data that could help realize their full potential. The Resource Description Framework (RDF) provides a flexible method to represent knowledge in triples, which take the form Subject-Predicate-Object. All data resources are described using Uniform Resource Identifiers (URI), which are global in scope. We present an OWL (Web Ontology Language) schema that expands upon the TMA data exchange specification to address this issue and assist in data sharing and integration.
HIVOntologymain.owl HIVO004 Public 580 0 10 1 OWL 010 11/05/2014 Hanfei Bao Description: In the processes that HIV causes in the development of AIDS, there are thousands of micromechanisims in molecular world involved. They include the combinations and decompositions of substances, the participations of the forces and energies of the molecules and atoms and their groups, the spatial movement and the effects of the spatial barriers or passages, the biologic effects of molecular distributions, sequnces or patterns and even the steric configurations. All of them constitute the variety of sophisticated pictures such as molecular trains, trees, loops or circles or feedbacks, oscillatings or fluctuations and forked roads (uncertainty points), and the huge and dymanic networks, at last. The author believes that HIV and AIDS ontologies are able to help know and understand the knowledge semantic networks better. Toward this end, HIV ontology will make the granularity of the elements (or entities) and relations (or object properties) detailed enough and develop a set of AIDS clinic ontology and calculation ontologies as the powerful assistant bases. The knowledge in ontology is expressed by the form of The Resource Description Framework (RDF), known as the “triple” ( “Thing1(URI) --relation(URI) -- Thing2(URI)”. Therefore ontology is mainly the computer readable and understandable knowledge resources. Ontology is esentially an ever-continuing work, the initial version of HIV ontology (HIVOnt006.owl) is published here. The is the main part of a set of ontologies on HIV and AIDS, a work being designed and developed underway.

Pathway Ontology PW Public 1,569 0 0 1 OBO 6.7 11/18/2014 Victoria Petri Description: The goal of the Pathway Ontology is to cover all types of biological pathways, including altered and disease pathways, and to capture the relationships between them within the hierarchical structure of a Directed Acyclic Graph (DAG). The five nodes of the ontology are: classic metabolic, regulatory, signaling, drug and disease pathways. An extensive survey of the review literature along with searches of existing pathway databases have been used to choose terms and their position within the tree. The ontology is continually expanding along with the development of Pathway and Disease Portals at RGD. Mapping of pathways in other databases to terms in PW as synonyms further increased the content of the ontology. It also provided the means to bring in annotations made by these databases and link to their sites via automatic pipelines built at RGD. The ontology allows for the standardized annotation of rat as well as human and mouse genes to pathway terms. It also serves as a vehicle to connect between genes and ontology reports, between reports and interactive pathway diagrams, between pathways that directly connect to one another within a diagram or between pathways that in some fashion are globally related in pathway suites and suite networks. Metabolic, regulatory or signaling pathway terms have associated terms for the altered version of the pathway and the level at which the alteration(s) may occur. Proteins with mutations known to affect a particular pathway can be annotated to the normal and altered version(s) of the pathway and to a disease pathway, if known. Both the provision of terms for the altered versions of pathways and the representation of disease pathway diagrams as a collection of altered pathways are unique to the PW ontology and RGD's pathway data. The Pathway ontology is distributed under the terms of the Creative Commons Attribution license version 3.0 Unported (CC BY 3.0), see for details.

Menelas Project Top-Level Ontology TOP-MENELAS Public 458 0 0 0 OWL 1.1 07/15/2013 Jean Charlet Description: The two main goals MENELAS contributes to are to (i) Provide better account of and better access to medical information through natural languages in order to help physicians in their daily practice, and to (ii) Enhance European cooperation by multilingual access to standardised medical nomenclatures. The major achievements of MENELAS are the realisation of its two functional systems: (i) The Document Indexing System encodes free text PDSs into both an internal representation (a set of Conceptual Graphs) and international nomenclature codes (ICD-9-CM). Instances of the Document Indexing System have been realised for French, English and Dutch ; (ii) The Consultation System allows users to access the information contained in PDSs previously indexed by the Document Indexing System. The test domain for the project was coronary diseases. The existing prototype shows promising results for information retrieval from natural language PDSs and for automatically encoding PDSs into an existing classification such as ICD-9-CM. A set of components, tools, knowledge bases and methods has also been produced by the project. These include language-independent ontology and models for the domain of coronary diseases; conceptual description of the relevant ICD-9-CM codes. This ontology includes a top-ontology, a top-domain ontology and a domain ontology (Coronay diseases surgery).

Immunogenetics Ontology IMGT-ONTOLOGY Public 1,412 0 0 0 OWL 1.0.2 07/17/2013 Véronique Giudicelli, Patrice Duroux, Professor Marie-Paule Lefranc Description: IMGT-ONTOLOGY is the first ontology for immunogenetics and immunoinformatics. It provides a semantic specification of the terms to be used in immunogenetics and immunoinformatics and manages the related knowledge, thus allowing the standardization for immunogenetics data from genome, proteome, genetics, two-dimensional (2D) and three-dimensional (3D) structures. IMGT-ONTOLOGY manages the knowledge through diverse facets relying on seven axioms, "IDENTIFICATION", "CLASSIFICATION", "DESCRIPTION", "NUMEROTATION", "LOCALIZATION", "ORIENTATION" and "OBTENTION". These axioms postulate that any object, any process and any relation can be identified, classified, described, numbered, localized and orientated, and the way it is obtained can be characterized. The axioms constitute the Formal IMGT-ONTOLOGY, also designated as IMGT-Kaleidoscope. As the same axioms can be used to generate concepts for multi-scale level approaches, the Formal IMGT-ONTOLOGY represents a paradigm for system biology ontologies, which need to identify, to classify, to describe, to number, to localize and to orientate objects, processes and relations at the molecule, cell, tissue, organ, organism or population levels. IMGT®, the international ImMunoGeneTics information system®, has been built on IMGT-ONTOLOGY. The version 1.0.2 of IMGT-ONTOLOGY includes the concepts of IDENTIFICATION and the concepts of CLASSIFICATION.

A class may be related to its superclass through a true is_a relationship (e.g., Polymyositis is a Dermatomyositis, which is an Autoimmune_Disease, which is an Immune_Disorder). Based on description logic, a class inherits all the Relationships (Object Properties) and Datatype Properties (if any) assigned to its superclass. In a few occasions, a class may have more than one superclass and belongs to more than one lineage.


Specific information may be available about a class, including Preferred_Name, DEFINITION, Synonym, etc. The following provides more detail on annotation information presented:
DEFINITION: A human-readable definition is provided for each class in the ontology and the displayed format is Owner|Definition (Source).
FULL_SYN: Synonym of a class in the ontology with type (PT: preferred term, SY: synonym) and source of this synonym indicated. Synonym|Type of Synonym|Source of Synonym is the format displayed.
ICD-10_Code: Code of International Classification of Diseases and Related Health Problems, 10th revision. ICD-10 is a detailed description of known diseases and injuries. It is published by the World Health Organization (WHO) and is used worldwide for mortality statistics.
ICD-9_Code: Code of International Classification of Diseases and Related Health Problems, 9th revision.
Class Name: Class_Name is used as a unique identifier by Protege-OWL, the environment where this ontology is being developed and therefore has to be OWL-compliant. Class_Name is composed of a string only made of digits, letters, underscores, and hyphens. A Class_Name cannot start with a digit.
Preferred_Name: A human-friendly and commonly used name in plain English.
Synonym: Synonym of a class in plain English, including those in plural form or British spelling. In contrast to FULL_SYN, no type nor source of synonym is indicated. Synonym is human-friendly and not OWL-compliant. A class may have multiple synonyms.
UMLS_CUI: Concept Unique Identifier in Unified Medical Language System that is produced and distributed by NLM. There are three UMLS Knowledge Sources: the Metathesaurus, the Semantic Network, and SPECIALIST Lexicon. The purpose of UMLS is to facilitate the development of computer systems that behave as if they "understand" the meaning of the language of biomedicine and health.

Relationships (Object Properties)

Relationships are properties by which one class is related to another class in the ontology. For example, "Population_Group" (a class) has_susceptibility_to_disease (a relationship) "Immune_Disorder" (a class). This box may be empty if no relationship has been used for modeling.

Datatype Properties

Datatype Properties are properties by which a class is related to a datatype. This box may be empty if no datatype property has been used for modeling.

Web-Service Interaction Ontology WSIO Public 31 0 0 1 OBO beta2 06/19/2014 Matus Kalas Description: Web Service Interaction Ontology (WSIO) enables automated interaction with more complex Web services that are typical for example within life sciences. WSIO is however independent of the application domain and relevant for both SOAP and REST Web services, and for batch execution engines in general. If the interaction scenario with a Web service is nontrivial (and incorporates session handling), annotation with WSIO concepts will enable automatic generation of client programs, scripts, or interactive applications with a graphical user interface. WSIO also enables automation of different ways of data transfer and data un-/compression or en-/decoding. We strongly discourage providers from developing complex interaction and data-transfer/compression scenarios, however when needed, WSIO may enable smooth automated interaction with them. Future versions will support more interaction scenarios. WSIO aims to serve also as a means to standardise the complex interaction scenarios primarily within both SOAP and REST Web services, and secondarily to apply also to batch execution infrastructure in general.

BioAssay Ontology BAO Public 3,340 0 0 7 OWL 2.0 11/18/2014 Stephan Schurer Description: The BioAssay Ontology (BAO) describes chemical biology screening assays and their results including high-throughput screening (HTS) data for the purpose of categorizing assays and data analysis. BAO is an extensible, knowledge-based, highly expressive (currently SHOIQ(D)) description of biological assays making use of descriptive logic based features of the Web Ontology Language (OWL). BAO currently has over 1000 classes and also makes use of several other ontologies. It describes several concepts related to biological screening, including Perturbagen, Format, Meta Target, Design, Detection Technology, and Endpoint. Perturbagens are perturbing agents that are screened in an assay; they are mostly small molecules. Assay Meta Target describes what is known about the biological system and / or its components interrogated in the assay (and influenced by the Perturbagen). Meta target can be directly described as a molecular entity (e.g. a purified protein or a protein complex), or indirectly by a biological process or event (e.g. phosphorylation). Format describes the biological or chemical features common to each test condition in the assay and includes biochemical, cell-based, organism-based, and variations thereof. The assay Design describes the assay methodology and implementation of how the perturbation of the biological system is translated into a detectable signal. Detection Technology relates to the physical method and technical details to detect and record a signal. Endpoints are the final HTS results as they are usually published (such as IC50, percent inhibition, etc.). BAO has been designed to accommodate multiplexed assays. All main BAO components include multiple levels of sub-categories and specification classes, which are linked via object property relationships forming an expressive knowledge-based representation.
