I have been busy installing Elda-common on a Raspberry PI 2. After getting it working (hurrah!) I would like to report the following:
The splitting of Assets and Common as described in the Reference
didn't do it. When I tried that, with a minimal configuration, Elda-common couldn't find the assets necessary for the markup of the query results. I solved this by copying the webapps/elda-assets directory to webapps/elda-common/lda-assets like it is done in Elda-standalone.
Thanks for your attention.
