Proper reuse of digital objects requires a licence. Well documented legal interoperability is a prerequisite for automatic distributed search and use of both the semantic artefacts and the individual terms/concepts and relations.
Although we are encouraging Open Source types of licences, preferably using Creative Commons 4.0 licencing, this recommendation doesn’t impact the choice but emphasizes the need for adding this information explicitly for both human and machine to avoid ambiguities on the conditions for reuse.

We highly recommend making semantic artifacts and their metadata openly available, to facilitate reuse and interoperability of data. A clear machine-reabale representation of the license of an ontology is needed. The absence of an explicit license might prevent others to reuse the ontology, even if the ontology is intended to be open.
AgroPortal's ontology metadata model offers several properties to store semantic artefacts license information (omv:hasLicense, later dct:license), access rights (bpm:viewingRestriction later dct:accessRights), more information on permissions and guidelines to use (cc:morePermissions, cc:useGuidelines) a well as copyright holder (bpm:contact later dct:rightsHolder).
The user interfaces suggest using RDF values from http://rdflicense.appspot.com/ to describe license information in a machine-understandable manner.

Short answer NO It is in our short term plans to include one though
