Metadata aggregation as a route to cross-federation inter-operation continues to be my main focus for the year, and yesterday I delivered a presentation on the subject at JISC's Federating the next generation event.
I think the talk went reasonably well; a couple of people remarked that they liked having the key concepts separated out and clarified. People even chuckled in the right places a couple of times.
As usual, here's a PDF version of my slides from the presentation:
There are a fair number of animated diagrams in this talk, and not as many words as usual. That might mean that some parts are hard to follow without hearing me talk. I'm going to try and get hold of the audio recording made at the time and will upload a slide-synchronised version of the talk later if possible.
