In both the GNAF Best Practice implementation report and NRW Best Practice implementation report, an issue has been encountered in relation to Best Practice 2: Make your spatial data indexable by search engines namely that there are millions of Spatial Things in each dataset and whilst the implementations create machine readable and indexable data for each Spatial Thing, the use of pagination to make the Spatial Things navigable for humans seems to impact the indexability.

In discussions in Lyon there was also some questions about the demonstrating the value of having each individual Spatial Thing indexable - however I believe there was reasonable consensus that allowing users to find a specific Spatial Thing and for machines to be able to create links between datasets containing information about specific Spatial Things was seen as having clear value - although the description of the value of the linking between spatial things or data about the same spatial thing could be improved in Best Practice 2.

I believe @cportele is going to look into the sitemaps approached discussed in Best Practice 2. We may also benefit from discussion on this issue from Ed Parsons.
