The Neurolex Wiki is a curated site; that is, members of the NIF and affiliated projects regularly review the content and may modify it as necessary. The Wiki was set up for the purpose of providing the community an opportunity to contribute categories and definitions to enhance description and access to neuroscience-relevant data. The concepts contributed on the Wiki are used to help build the NIF ontologies.
When new categories are created or new relationships added, the NIF curators determine whether the category needs to be added to our ontologies. This determination is made based on whether we have a current ontology covering the domain, whether the category is unique, that is, it does not already exist under another label, and whether it is relevant to the mission of the NIF. If these conditions are met, the category is added to the NIFSTD ontology.
Categories that are added to the NIFSTD receive a unique identifier, usually of the form nlx_####. If the category already exists in a community ontology, the identifier assigned in the original ontology is reused. If a category is determined to already exist, the label used is usually added as a synonym to the existing category. In this case, the original category page is usually deleted. Any changes to a page can be viewed by clicking on the "history" tab.
