 Okay, well regarding metadata, Australia Entity Data Center, we use the DIFF metadata standard, which stands for Directory Interchange Format, that's the standard that was developed and maintained by the Global Change Mastery Directory. There are a part of NASA based out of the Goddard Space Center in Maryland just north of Washington DC. The reason why we use this standard is because it's the standard that's used by the entire international Antarctic community. There was about 15, 16 years ago, the Antarctic community got together, decided they needed to settle on a metadata standard, rather than using disparate standards that each countries were looking at, and DIFF was the one that was chosen, and as part of that, the Global Change Mastery Directory, they provide metadata support to the Antarctic community as well as providing an Antarctic metadata portal. Currently, we have about just over 2,500 metadata records, 90% of which point to data, a lot of which is public, although not all of it because we do have some commercial confidence data, and obviously we don't make data public until the scientists have managed to have a chance to publish themselves. As for our data, as I said, we have that in the DIFF format, which you can see in blue up the top, but we also convert that to a large number of other formats. On this little page here, all the blue squares are metadata formats, and the red squares are metadata repositories. We convert our DIFF standard into the ISO 191.1.1.1.5 standard, which is just listed there as ISO. We also have a marine community profile version of that, and an anzlic profile version of that, and we also have this other funky one, this ANZ version, so that's just an intermediate step. Organizations then take our ISO ANZ metadata record, and then they convert that into RIFCS, which is then made available via the ANZ repository. So as you can see, I've listed the organizations I can think of that harvest our metadata records. So you can see there's quite a few there, most of them just take the plain ISO. I have just realized I've put Bob and Thomson Reuters in the wrong section because they actually take our plain DIFF metadata, they don't take the ISO, they just take the regular DIFF. So anyway, that's all by the by. So but what happens here, one thing I should point out is that most of these, all of these people that are harvesting our metadata record, they do so via something called WebDef. So we have all of our records that are in web-accessible folders, and we put those up there and then people just grab them and they harvest them when they're ready. I should point out that the Australian Special Data Directory, they require us to use geo-network for us to get our records into their system, but we haven't quite got that running properly yet, so that's more of a sort of wait and watch this space. So the reason why we do all this harvesting is because it helps increase exposure not only for us, but also for our scientists. So the more metadata repositories we can get our records out into, the greater the spread and dissemination of all these metadata records there is. And that means that that gives our scientists much more chance of their data being noticed and therefore being picked up by the scientists, and then obviously they get cited or it could lead to further collaborations for the scientists themselves. Okay, there are a few issues though with this. At the top point there, as I say in our experience, harvesting is usually a bit more pull than push. So whereas people like BOM or ANZ or whatever, they're grabbing their metadata records off us when it's convenient for them. Some organizations are good at doing that regularly or automatically. Others, they don't do it quite so often, and that can lead to sync problems because we're updating our metadata records all the time. And if somebody hasn't harvested our records for a few months, then the set that they've got obviously gets out at date. So we sort of monitor that a little bit every now and then, but that's just more of a, I remember to go get it out in the process rather than anything being automatic, so we could probably improve that. Also, there's a slight issue with re-harvesting, which I'll just show you in this diagram. So I've grayed out most of it, but what happens here is that ANZ, you can see they get our metadata from us, so it comes down through DIFF and into ANZ. But ANZ also harvest metadata records from this ocean data network, and they grab an ISO version of our data. And likewise, SUSE, the Southern Ocean Observing System, also harvest metadata from the AODN, as well as getting it directly from us. So the problem here is that we then have two copies of one metadata record, which can end up in the same system. And sometimes these records aren't quite the same, and that's because other organizations like the Southern Ocean Data Network and ANZ, obviously they tailor the metadata records very slightly to suit their purposes, which is fair enough because as their repository, it's their catalog, so they should make them look sort of how it fits for them. But what that sort of has the effect of is that when the records all end up in this other next repository, is that even though they're the same records, they won't look quite the same. So we've sort of tried to address that by adding a UUID to all of our records so that that gets preserved all the way through so that users can then, at least if they suit your records, which look to be similar, they can compare the UUID and go, okay, that is the same record, so I don't even worry about looking at this one. And we also try and add a point of truth URL to all of our records to point back to the Australian Antarctic Data Center original, so that at least users can then get back to their master record. Okay, so that's basically it for HUB Sting and for our project cycle. So thanks for listening.
