 So this is just a very brief overview of some of the things that we've been doing in research vocabularies Australia over the last six months or so. And perhaps some of you have actually seen some of this already just to put a bit of spin on it, I guess, and to maybe talk about some of the things that we like and put a bit of work into to make the system better for our users. So just these four points so far and then anything else that you want to know about, you can ask Joel. So work on the GCMD science keywords and our republication of those in research vocabularies Australia. A little tweaking to the link data API, also known as CISBOG that we've done for our service. A subscription notification system which we really like you all to use and the registry API which is perhaps not for everybody but if you want to do interesting things it's a means to do that to take advantage of the vocabularies that are in RBA. But so first GCMD science keywords. We are a long time consumer of the NASA GCMD science keywords and we have had a version of it, some of the keywords published on RBA for some time. We wanted to do that a little bit more systematically and to republish them in a way that it's easy for our users to consume, reuse, repurpose. And so that's what we've done here. I'm happy to admit a certain naivety on my part in terms of just getting my head around what these keywords are and how they work and the different vocabularies. There are, depending on how you count them, 11 or 12. Yeah, let's say there are 11 vocabularies that you'll see in RBA. Plus a 12 one that I put together that combines all of the rest. So you can make use of that in the vocabulary widget. You can search for these things in RBA and get a list of them through the API. We'll see an example of that later. We've added a few triples into the RDF to support the vocabulary widget in which you are free to either to use yourself or ignore up to you. And because it's published through RBA, it's available through all the usual types of endpoints. So just a straight download and through the usual RDF formats, RDF XML, turtle, etc. Sparkle endpoint for Sparkle queries and through the link data API, aka as well. And we've committed to republishing versions as they come out, what I would call major releases, but they're in a sense dot releases from NASA people. I think we're currently on 8.6. The version numbering is interesting in the sense that there are these minor version numbers, 8.6 and so on that come out once a year, but then there are monthly, well actually more than monthly updates. They make updates from time to time and then there's a monthly document that's put out that summarizes what's happened in the last month. So we look for your feedback as to whether you need those intermediate versions to be available or whether you're happy to just make use of the latest dot release, which is a major release that comes out every year. So we have some documentation. That page that's in the URL there, it's in the presentation. Yes, and we will, of course, this presentation will be available and so you can click on the links and follow that. So we do have some documentation on our documentation site. It looks like this in RVA, or at least the first bit of it, just if you just search for GCMD, you will find those vocabularies. And here's one of them, an usual RVA format with the version shown in the left-hand pane and the release download and other endpoint options there. So this is a start in a sense of the republication of these new versions. So there's only one there. We'll be added as the GCMD team put out most of. So we did put out something about this in the most recent ARDC newsletter email. Perhaps it wasn't quite so obvious. I think it got a bit buried. But we will put this out again through some of the other notification channels as well. Link Data API, this is a case where the Office Shelters functionality we had made available, but it wasn't working so well, so we decided just to hide the functionality until we could make it work well. And so we've now made it work well. And it's to do with some of the filtering capabilities. So the HTML pages that you get through the Link Data API are quite good already. I let you do all sorts of filtering, but there was a certain filtering that wasn't working, but it is now. And you'll see that here in an example where there are dates, and these dates will come through in vocabularies that our users have published out of the full-party project, but also do appear in other projects as well. So dates that are marked as dates... Do you actually see my mouse as I move it? You do. Okay, so if I just... So these less than greater than signs are filters and they weren't working, but they are now. So let's do an example. If I click on this greater than sign... Okay, my mouse is not... You're not seeing where I'm pointing with the mouse actually at the moment. Never mind. Click on the one that I've got an arrow pointing at, and that will filter to the concepts that have created a time greater than or equal to that time. So do that, and the list is now filtered to those concepts. And the icons now change to show that you see the green background of that. So there's a reversion. And you can also keep going. So you can keep stepping through and find concepts greater than other values that are shown there. So that's nice. It's a nice way of navigating vocabulary to see how concepts have evolved over time, descriptions or whatever has changed. Next is subscription notification system. It's a tiny little button on the screen, which I'll show you, but there's a lot happening under the hood. So in response to user request, we have a means of subscribing to vocabularies, either individual vocabularies or all the vocabularies published by a particular organization, or all vocabularies in the system, and also means of subscribing to updates about the service. And if you subscribe, you get a customized for you email every week with your notifications. And there's an interface for managing your subscriptions. So there's a tiny little button on one of the pages. That's what it's about. And if you click that, you get a little dialogue pops up, and you can select whether you want to subscribe just to that vocabulary or from that, from the publisher, specifically the owner of that vocabulary, or all vocabularies. And you can subscribe to three individual vocabularies or some combination of owners. It's very flexible. And you also have the opportunity to subscribe there. There's a checkbox for system updates, service updates. And all you have to do is put in an email address, and you will start receiving notifications. And they go out on the Wednesday or Thursday mornings. It's the Wednesday mornings. And that service is available both on our main production server and on our demo server. Here's a sample, one of the emails that comes out every week. I'm going to have the time. One of them. Some of them. Okay. I will zoom in on this in a sec. This is just an overview of one of the more interesting emails that came out. This is showing my subscriptions. It's both an HTML and a plain text email. So if you're a mail reader with somewhat degraded, you will still be able to read it. Where we can put in links, hyperlinks to vocabularies, they are included, so you can click on the vocabular and go straight to it. And there's another link at the bottom to manage your subscriptions. So let's just zoom in on this one so you can see a bit more clearly. For each vocabulary that you get any notification about, you'll see which versions have been, a lot of the new versions. What versions have been, if any, have been deleted. And where there's been an update to a version, you can see it shows you which of the fields has been updated. Not very exciting, but it can get exciting. Somebody has done something interesting there. And of course, if you have subscribed to notifications from a particular owner, then you get notifications about new vocabularies as well. The Manage Subscriptions page, so if you do click on the link at the bottom of the page, and so as you get a page, it looks like this and it shows you a list of checkboxes that are your subscriptions. And then you just check what you want to unsubscribe to and then click the button and you're unsubscribed. Very straightforward. So that's all user focus in terms of the portal. Through the backend, through the registry, we now have a public accessible registry API. So this was a major, major, major effort to separate the front-end and back-end of the system and to very strictly keep that separation so that all of the main functionalities is in the registry and the portal makes calls to a registry API. So we have quite a lot of documentation about this now. It's an API for the metadata catalog. So we know that certain people want more and more and more and that's fine. In particular, APIs to access vocabulary data and that's on the list of things. But this is particularly an API for the metadata catalog. So the list of vocabularies that's in RBA getting access to titles, descriptions, notes, etc. and this diversions and their status. The documentation will take you through what's available. But in particular, I'll show you a slide of the swag user interface which is a really nice convenient way of just getting started with it and then the presentation also has a link to just a reasonably straightforward example of one way of using it. But there are many others. So lots of documentation pages on our documentation site. Getting started, high level intro description of the model entities that are in there. How you access it, different means of accessing the API. Details of particular methods and we have a page of some sample workflows. Examples if you like a cookbook to help you to get started with it. Here's the swag user interface. It's a very convenient I use it myself all the time very quick way of interacting with particular API methods that's actually generated from the definition of the API methods. That's very nice. And the link in the presentation is to Jaysfiddle. If you're not familiar with Jaysfiddle let me tell you what it's about. It's a means of very easily well if you know JavaScript and HTML prototyping little bits and pieces of user interface. And my colleague, wonderful colleague Joel has done this little one. And simple little example little drop down list where we have used the API search method to get a list of vocabularies out of RBA that are published by GA I think. And then when you make a selection you will get the vocabulary widget and list of concepts there. And if that's hierarchical then you get usual vocabulary widget means of expanding the next level and so on. So there's a very brief intro to the API We welcome your feedback and please do get in touch for new features and anything you like, like don't like. We love to hear things that you like. That's always good. But anyway, do get in touch and that's the standard services email being in touch with us. And that is it.
