This Wiki takes advantage of the Semantic Mediawiki software and the Halo Extension and has loaded all the NIF ontology classes. Many of the annotation properties associated with those classes have been tagged with properties here. Restrictions have not yet been ported over. However, in this current version, most classes just have the NIF id and the parent class/category associated with them.
The Wiki version of the NIF encodes classes as "categories", as in the standard Wikipedia. These class categories themselves have editable pages. This therefore allows anyone to update the definitions of the classes.
This Wiki also allows other "instance" articles to be tagged with those classes. Properties between classes or between "instance" articles can be defined as well. This allows individual terms within "instance" articles to be tagged with these properties. There are a few examples of this below.
By tagging parts of a page with a property, a query mechanism can reshuffle the data within those pages in tables or by generating dynamic lists. Some examples of this are also below.
 Recent Updates
February 12, 2009: Fixed NIF molecule to remove the duplicate trees from the original SAO import. Moved most classes to "Biomolecule"
February 2009: Removed many of the duplicate classes from NIF Cell. Set up classification of neurons by neurotransmitter
On November 10th, 2008, NIF Pedia was renamed NeuroLex and moved to NeuroLex.org. A summary of the changes is available here.
On August 27th, 2008, NIF Pedia added even more properties to existing classes.. Also, definitions are now better formatted with proper punctuation that was causing formatting problems before. Check out a complete list of properties here and here.
On August 25th, 2008, NIF Pedia replaced the usage of "birnlex_definition" with "definition" and "nifid" with "id". Many other properties were added. Check out a complete list of properties [http:/neurolex.org/wiki/Special:Properties here] and here.
On August 21st, 2008, NIF Pedia imported several pages from Wikipedia from the Neuroscience category. Some of these pages have been marked up with NIF classes/categories for demonstration purposes (see below).
On August 20th, 2008, NIF Pedia was updated with 95% of all NIFSTD classes. More definitions were tagged with property tags. Properties such as "birnlex_definition", "comment", "editorialNote", "externallySourcedDefinition", and "synonym" have been copied from the NIF ontology for all classes where they are available. This has allowed some tables to be automatically generated through a built-in query mechanism (see below).
