Sounds interesting. Do you have a current eta for the next release?

When I've completed ACME's sea trials, I'll have pretty much all I need, I reckon. I'm following a couple of approaches towards integrating metadata: Slimcoin's OP_RETURN approach and, just for completeness, Datacoin's 128Kb-per-tx data field.

ACME instances:

http://tessier.bel-epa.com port 5064 for Slimcoin and port 5059 for Datacoin.

I haven't yet enabled caching so you'll need some patience for the occasional sloooow page load. Not everything works but the Slimcoin adaptation is further along than the Datacoin adaptation. The key work is taking place in Publications. In Slimcoin, txs with OP_RETURN data are retrieved and the data displayed verbatim (lacking a show me only OP_RETURN values for tx made by addresses I choose to specify ). In Datacoin, I have identified the tx with data fields (4300-odd) and am trying to MIME-typify the stored binary (could be a JPEG, DOC, ZIP, *anything*) to present a paginated list (as well as an only these addresses filter). The Datacoin dev devised a solution using Google's protocol buffer library but I speed-read one post that concluded the approach wasn't powerful enough. I'm just verifying for myself that is the case before settling on the RDF-based approach.

Datacoin is a bit of a puzzle and potentially a cautionary tale from my perspective. There's a thread from three years ago which pretty much covers it, provides answers, functionality, 3rd-party support services, everything you'd think was necessary for this to get off the ground, yet only 0.2% of the not-quite 2m blocks+tx have non-empty data fields and a significant percentage of those are noise, i.e. hold no discernible value (although the value may just be in the timestamp). So why didn't it take off? I need an answer to that question before going any further in terms of people using the blockchain as a publishing device.

(the gory details are in my posts passim to the Slimcoin and Datacoin bct threads, not written it up yet, sorry).

Cheers
