Key features of Ontohub:
===Start===
+
*OntoHub is an ontology repository that supports the ontology development and maintenance along the whole ontology lifecycle.
 
+
* publishing & retrieval: OntoHub is a free ontology repository that allows you to publish your [[ontology]] and find existing ontologies that are relevant for your work.
The home page of Ontohub provides access to all public repositories, ontologies, symbols, logics and ontology mappings stored in this hub of distributed, and yet interconnected, ontology repositories. Recently updated repositories and ontologies are listed as well.
+
*development: OntoHub supports ontology development. Since OntoHub is a based on [[Git]] repositories, OntoHub supports ontology versioning, branching, and merging.  
 
+
* evaluation: OntoHub is designed to be a platform for ontology evaluation tools. The goal is to support all kinds of evaluation; including syntactic validation, best-practices evaluation, and regression testing.
===Sign In===
+
* multilingual : OntoHub supports a wide variety of languages and [[logic]]s. The same ontology may exist in more than one one language. OntoHub supports the automatic translation between languages.
 
+
*open: OntoHub is based on open source software.
The full functionality of Ontohub ([[ontology]] and [[repository]], creation, collaborative editing and development of ontologies, [[mapping]] across ontologies, visualisation, and evaluation) is available upon sign in. Every registered Ontohub user can modify and adjust its own version of interface, i.e. specific and highly personalised access to the repository content.
 
 
 
===Repositories===
 
 
 
Besides serving as an ontology repository, Ontohub is also a hub that links other ontology repositories. Ontohub provides a single web interface to access various ontology [[repositories]], either hosted or mirrored on Ontohub. The button ''Repositories'' (on the menu-bar) leads to the page where all public repositories are listed and the access to their content provided. In addition, Ontohub allows creation and hosting of new repositories, the function available to all registered Ontohub users. Along the opportunity of creating a new repository, Ontohub users can get advantage of the Ontohub collaborative environment in order to develop ontologies and/or repositories in either problem or domain oriented manner. Thus, Ontohub supports reuse of ontologies stored in other ontology repositories and creation of new repositories that organize ontologies resulting from the activities of a team focused around a particular project or a specific task.
 
 
 
Ontohub repositories are stored as [[git]] repositories. Git provides a persistent storage and version control for ontologies,
 
as weill as access to Ontohub repositories via the usual git tools.
 
 
 
It is also possible to create private repositories. These are visible only for users who have read-permission for the repository.
 
 
 
===Ontologies===
 
 
 
Ontology search can be performed either over whole Ontohub content ('Ontology' tab on the menu bar) or over ontologies stored within a particular Ontohub repository (Ontology browser on the page of a particular Ontohub repository).
 
 
Ontology retrieval is done by typing into the ontology browser one or many of the available search criteria:
 
 
 
* Ontology name
 
* ontology acronym
 
* ontology language
 
* a symbol or a label that an ontology contains
 
* a particular domain (category) that an ontology belongs to (e.g. space, biology, etc.)
 
* ontology type (e.g. upper, domain, task, etc.) Please note that this feature has not been implemented yet.
 
 
 
Since the search engine uses [[metadata]] to retrieve an ontology, all Ontohub users are encouraged to specify metadata about their ontology during the ontology upload. Having described an ontology domain, type, task, etc. increases findability of an ontology.  
 
 
 
See [[FAQ]] on how to submit an ontology.
 
 
 
===Categories===
 
Ontologies can be categorised. Ontohub's [[category]] system is maintained as an OWL ontology in Ontohub itself, see
 
[http://ontohub.org/meta].
 
 
 
===Logics===
 
Ontologies can be formulated in various [[logic]]. Ontohub supports a number of different logics, among them
 
OWL, RDF and Common Logic.
 
 
 
===Mappings===
 
Under the [[mapping]]s tab, you can see all mappings. Mappings always have a source and a target ontology, and provide mappings or relations between the symbols of these ontologies.
 
 
 
Currently, new mappings can only be created using e.g. an interpretation or an alignment in a [[DOL]] file, and uploading that DOL file.

Welcome to Ontohub,
the free and open ontology repository engine.


Ontohub is an open ontology repository which supports organisation, collection, retrieval, development, mapping, translation, and evaluation of a wide array of ontologies formalised in diverse languages.

The Ontohub team is looking forward to providing technological infrastructure for the forthcoming FOIS 2014 Ontology Competition. Accordingly, several new features are going to be launched on the Ontohub soon.

This wiki entrance aims at providing instructions and support to the Ontohub users. See also FAQ.

Key features of Ontohub:

  • OntoHub is an ontology repository that supports the ontology development and maintenance along the whole ontology lifecycle.
  • publishing & retrieval: OntoHub is a free ontology repository that allows you to publish your ontology and find existing ontologies that are relevant for your work.
  • development: OntoHub supports ontology development. Since OntoHub is a based on Git repositories, OntoHub supports ontology versioning, branching, and merging.
  • evaluation: OntoHub is designed to be a platform for ontology evaluation tools. The goal is to support all kinds of evaluation; including syntactic validation, best-practices evaluation, and regression testing.
