Two recent presentations are now up on the WSTIERIA web site, which also now links back to this blog. The first is a short overview of the project (PDF, PPT) presented in a ten-minute talk at the AIM Programme start-up meeting, the second is a slightly more in-depth look (PDF, PPT), with a block diagram showing how a facade can handle web service authorisation. This was an invited talk at last week’s Open Geospatial Consortium (OGC) Technical Committee meeting at Frascati in Italy.
