<br>
As far as I’m aware, there is no ongoing work on SimpleTimeSeries.<br>
<br>
As you might recall, at the June 2015 InterOp, Enrique Solano presented some thoughts on SimpleTimeSeries (see <a href="http://wiki.ivoa.net/internal/IVOA/InterOpJune2015CSP/TimesSeriesV3_esm.pdf" rel="noreferrer" target="_blank">http://wiki.ivoa.net/internal/IVOA/InterOpJune2015CSP/TimesSeriesV3_esm.pdf</a>). At the time, his conclusion was that STS was inadequate for his use case; he suggested using Spectral Data Model v2.0 instead, with the caveat that even SDMv2 may be inadequate for complex cases. As of now, SDMv2 has not yet been officially anointed as an IVOA recommendation.<br>
<br>
Enrique, have you done any further work in this area since your previous report? If so, would you be willing & able to report on it in Cape Town? I don’t see your name at <a href="http://ivoa2016.sa3.ac.za/participants/" rel="noreferrer" target="_blank">http://ivoa2016.sa3.ac.za/participants/</a>.<br>
<br>
At the same time, you will have seen Jiří Nádvorník’s recent message on the Czech effort to represent time series within CubeDM. Jiří, if you’ll be in Cape Town (again, I don’t see you on the participant list), I very much hope you’ll be willing to give a summary of this work; if you won’t be there, maybe we can persuade Petr to do so instead?<br>
<br>
It seems there are now several folks actively working on making time series data available through the VO. This is certainly outside my area of expertise, but TDIG should be the ideal forum to pool interests and knowledge. If anybody wants to step forward to lead such an effort, that would be great; otherwise, lets get together during the TDIG session in Cape Town to discuss how we can best move forwards.<br>
<br>
Cheers,<br>
<br>
John<br>

It would of course make sense to publish them in a homogeneous format as this would allow generic tools to offer at least some preview and visualization features. I was however reluctant to invest time in this as I was unsure of the potential adoption of this standard. Does anyone serve (or plan to serve) time series in SimpleTimeSeries format?<br>

>> - Do either VTP or XMPP really properly fill the niche? Twitter are distributing mind-numbing volume of event data over HTTP — why aren’t we?<br>
>> - Tim Staley announced his voeventdb service for archiving and querying VOEvents to this list in January. Unfortunately, Tim won’t be at the meeting, but he’s promised to send a few slides. Has anybody tried this service? Do you have feedback? [I was using it just this past Sunday. Works great!]<br>
>> - I spent much of this afternoon sitting in an LSST discussion about their plans for announcing transients, touching on the format and content of alert packets and the transport mechanism. They’ve already announced ambitious plans for what they want to include in events (see <a href="http://ls.st/lse-163" rel="noreferrer" target="_blank">http://ls.st/lse-163</a> p29), and they aren’t backing down. What can we do to be ready?<br>
