-The backbone of Ontohub categories is The International Standard Classification of Education ([http://www.uis.unesco.org/Education/Pages/international-standard-classification-of-education.aspx ISCED]). ISCED is a member of the United Nations International Family of Economic and Social Classifications and is the reference classification for organizing education programmes and related qualifications by levels and fields of education. The final draft of the recent ISCED version (June 2013) provides a hierarchy of educational domains. ISCED was selected among several other classifications, as the most appropriate reference classification that specifies knowledge-subjects, i.e. categories of knowledge-domains. The reference classification was extended with several categories which are not originally contained within ISCED, e.g. Space, Time, and Process.

 The submission of a new ontology into Ontohub consists of the following steps:
-'''a'''. Register/'''sign in''' ontohub.org
+'''a'''. [[user|Register]]/'''sign in''' ontohub.org
-'''b'''. Select an existing '''repository''' that fits best your specific target domain, task, and ontology type; All public repositories are listed upon clicking on the 'Repository' button in the main menu; alternatively, it is possible to create a new repository (as described in the section below); certain repositories are 'read-only' while others allow editing of the repository content;

-'''c'''. If uploading an ontology to the existing repository you will need to get a '''permission''' via requesting the editing rights; the permission is provided by the administrator of the repository ('owner'); After selecting (or creating) an appropriate ontology repository and acquiring the editing rights, the ontology upload can proceed through the use of file system.

-'''d'''. The ''''Edit'''' button appears on the page of each repository for which you have the editing rights. 'Edit' button leads to the interface with the editing option. So, the first step in editing is to to confirm that you want to 'Update repository'. The next step is to go to the section 'Ontology files and related files', where you can upload your ontology as a new file. The information provided there in gets stored into the file system, which can afterwords be accessed at the 'Ontology files and related files'. You might want to upload your ontology into an already existing folder that stores ontologies of your interest. In that case, in the section 'Target directory' you will need to type the exact name of the directory in which you want to store your ontology file. Into the section 'Target file name' you will need to type the ontology name together with its correct extension, e.g. name.owl, name.clif etc. A message that accompanies upload is optional but desirable as it can be helpful in tracking the history of activities and changes in repository. The next step is to 'Upload file'.

-'''e'''. Since your submitted file is recognised as an ontology (via its extension), you will need to provide '''metadata''' that describe your ontology: ontology name, category (domain), ontology type, formality level, and a specific description. The inserted metadata are helpful in classification of ontologies in repository and their easier, a task specific retrieval.

The inserted metadata are helpful in classification of ontologies in repository and their easier, a task specific retrieval.
-When selecting metadata that describe the domain of your ontology you can select multiple fields (''''Categories'''') that will help to characterise your ontology as specific as possible. For instance, if an ontology is about anatomy of a biological species, then the appropriate categories would be 'biology' and 'space', while a geospatial ontology can be associated with the domains 'geography' and 'space', an ontology that describes chemical structures would be associated with 'chemistry' and 'space'.

 ''''Ontology type'''' and ''''Formality level'''' provide specification of your ontology as a domain ontology, an upper level ontology etc. Please note that the classification of ontology types and formality levels mostly follows the OMV specifications. Modifications and revisions to this classification are work in progress.
