== '''Outcomes''' ==
'''VRE'''<br>
G. Coro demonstrated the current development version of the VRE. <br>
The team was positive about progress made so far. Trends on the basis of absolute Nr of records will be one way but we now need to explore additional methods<br>
T. Webb made suggestions to make it possible to select multiple areas, select by taxonomic group and upload a list of species.<br>

'''Common species'''<br>
We had some discussions on the definition of common species. Many factors play a role, such as coverage in time, abundance, geographic spread etc<br>
T. Webb and OBIS are currently exploring alternative ways to identify common species<br>
P. Pagano proposed to look at TF-IDF methods to rank species in datasets, but they need to check how much resources are required to develop this method before they decide to commit in this.<br>

'''Ways Forward'''<br>
OBIS will be asked to evaluate the VRE once it is in production mode.<br>
OBIS and T. Webb will continue testing their methods on selecting common species and see if they produce any meaningful results<br>
If these additional methods prove to be a value the specifications will be shared with the development team to implement it in the VRE<br>
CNR will consider the suggestions from T. Webb to improve the VRE functionalities.<br>
