 Hello everyone. I'm Natalia Ackens. I'm from from EIMOS down here in Hobart. So EIMOS is an Integrated Marine Observing System and I think I put my hand up a little while ago to speak on vocabulary reuse within the vocabularies that I help to manage. I'll sort of, I need a short talk but and I'll keep it, I'm not a very technical person anyway but I'll keep it kind of sort of more sort of the broad concepts and just sort of an overview of of our experience and the way that we do things here. So I'll give a bit of an introduction to the AOD and EIMOS. I'll speak a bit about the AOD and vocabularies that we have. I've touched on some governance that we have here. An introduction to the BODC and I'll explain who they are when once we get there. And then I'll have a little bit of an end one of our vocabularies which does reuse vocabulary terms from another vocabulary. So I'll sort of go into that one in a bit more information or a bit more depth. So the AOD is one of the increased capabilities in Australia. So the marine based one. So it's not relevant to vocabularies but just an idea to sort of look at the range of data that we're dealing with. So we have a number of facilities that are collecting data for us in the marine space. So basically covering spreading over biological chemical and physical parameters. And I actually form part of our data management facility which is called the AODN which is the Australian Ocean Data Network. So that's just a bit of an overview just so that you you know where we're coming from and what we're here to sort of provide to users and what we need to describe with our vocabularies. So here at the AODN we're one of the early organisations that used research for vocabularies Australia through ARDC. And here are some details on a few of the vocabularies. We do have a number, a couple of others but these are the main ones that we publish. And so just to give you an overview of the size of each of the vocabularies. So we've got a few of these here. So how many concepts are in each of the vocabularies? What version number we're up to with those? And then of course this is about you know we're sort of touching on reuse of vocabularies. I've listed under each or identified under each particular vocabulary where we reuse terms from and as you can see that well most of them are from the BODC which is the British Oceanographic Data Singer and I like I said I'll explain a little bit more about them shortly but we're pulling terms from various different places within the BODC and we also have some overlap with some other organisations but you can see there's quite a diversity there and some vocabularies reuse all their terms partially so there's sort of a breadth in what we do there. So and like I said in the introduction I'm going to focus in on the instrument vocabulary that we have. It's sort of a somewhat sort of large one with 272 concepts in it. We're up to this version 2.1 and we reuse terms from two of BODC's vocabularies online so I'll touch on that later. So before I sort of go into that sort of side of things I wanted to give an introduction to the use of vocabularies within the AODN so here's a screenshot of a metadata record in GeoNetwork. It's quite small text you don't need to worry about it too much but the organisation vocabulary we use to mark up details and contact details of people. Within our keywords we also use the organisation vocabulary to identify the different facilities within IMOS. We mark those up in keywords and we also have information on data parameters in our metadata records and we pull the information from our discovery parameter vocabulary. We have a platform vocabulary and an instrument vocabulary and whilst I haven't circled it we also have our units of measure so we pull all these terms from a controlled vocabulary so we do things that way with the metadata so and then for those that are familiar with the AODN portal this is a way of discovering and accessing a large portion of our data holding so not everything is here but a great portion of IMOS data is here so and I should have touched before too that whilst the AODN manage the IMOS data that is coming in from the different facilities we also provide access and discoverability of all other not all other but you know a lot of other marine resources and data collected by other organisations through the Australasian regions so and the AODN portal is one of the main ways of discovering some that data not all of it's discoverable there but we do have everything in our metadata catalogue so the parameters also the vocabularies that are marked up in the metadata are also used to to drive our search feature when when users are looking for a data collection so they're able to use faceted search in with well regards to parameters organisations and platform and all this information is pulled from the metadata record and pulled from those controlled vocabularies that we manage in terms of our concept reuse sort of you know our etiquette that we we have set out so a previous colleague of mine Kim Finney was instrumental in setting up a lot of our vocabularies initially with ARDC and has put together we have a sort of an internal vocabulary governance guide that that we refer to and and we touched on on what our our reuse etiquette would be and so sort of covers things such as vocabulary creators that we're talking about us internally we're encouraged to reuse before establishing terms from scratch this reuse improves potential for interoperability and we've purposefully sought to reuse vocabulary terms where it's appropriate to do so in doing this the original concept URLs have been retained so that the term resolves when each of those concepts is individually accessed to its original point of truth and at the scheme level the vocabulary scheme URLs they resolve to the research vocabulary Australia endpoint and display all the concepts both with the AODN basemain so domain so we do have concepts that we've produced ourselves and then any other domain from which concepts have been borrowed so we try to do that so in terms of individual concepts when we do create them we use the concept URL as is description items such as pref label and definition copied for the concepts origin and then we make sure that the publisher and source identify the original publishing entity so that we make sure that information is is captured within the concept so I mentioned before that the majority of our vocabularies reuse terms from vocabularies from from the BADC so the British Oceanographic Data Centre they're based in the UK and they operate NERC Vocabularies Service so National Environment Research Council so which provides access to a range of controlled vocabularies and they cover a broad spectrum of disciplines of relevance to the oceanographic and climate community so within their their vocabulary server there's a range of management of those vocabularies some are totally managed by the BADC others are managed on behalf of other organizations and some are fully managed by external entities so there's a range of vocabularies on access or able to be accessed there so I mentioned that that sort of sort of delve a bit more into one of those specific AODN vocabularies just sort of explain a little bit more our sort of our workflow and our our use of external vocabularies in this so so this relates to the AODN instrument vocabulary we've published that on Research Vocabularies Australia that's the URL for that and I'll give you a show your screenshot of that shortly and it reuses terms from two of BODC's vocabularies one is LO5 which is their device category so it's kind of more at the top level the concept so a more of a broader concept level and then L22 which is which is more specific and sort of more at the description of models and manufacturer details so in terms of our vocabulary our TOPS concepts borrow terms from LO5 and our narrower concepts use terms from L22 so here is a look at the AODN instrument vocabulary in Research Vocabularies Australia sort of the landing page of that you can see we've had several versions since we produced this vocabulary we're up to version 2.1 and then if those that are familiar with Research Vocabularies Australia you can have a look at the terms within that vocabulary and search within them further down that page so I've got a screenshot of that one as well so this is sort of just a snippet of of the concepts that we've got within this vocabulary so like I said the the top level concepts that we have there are things such as you know sort of a category level instrument so things such as flow meters and flow cytometers and then our narrower concepts get down into the the details about models and manufacturer details so here's an example of of the seven fluorometer narrower concepts that we've got in this vocabulary and you can sort of see the sort of information um that's sort of gathered from those in terms of the title we have a look at um one of those um that the the text is a bit hard to see I'm afraid but um if you have a look at that um as previously said in terms of what we what we do when we create these terms and by reusing these vocabularies so um we retain the URL from BODC we make sure that we identify that the BAC is is the publisher and what the source of that term is which is which is the L22 vocabulary from there and then we also make sure that things such as definition um also match up with what the BODC have put in their vocabulary so so this is what our term looks like through um RVA and into sysbox so the display of that term if you have a look at that term in the BODC um their vocabulary so um you can sort of see their their pref label their definition I've just cut that off just for the ease of um visualization and um also the information that that has already been determined by this vocabulary is is for this particular instrument what are the the broader instruments um what are the instruments that are you know the next level up so this information is really useful for us when when creating our um our vocab terms because all this work's already been done for us they've they've done all the mapping already so um in terms of broader and and related concepts within their um their vocabularies so in terms of the workflow um that that I that I follow within the instrument vocabulary um basically starts off with determining the need for a new term if it doesn't currently exist within the aodine instrument vocabulary I search the relevant BODC vocabulary to check for current whether that that term currently exists in the BODC so and depending on whether this is a top level concept or a narrow one I will look within the the the relevant um uh vocabulary um the here's sort of a um before when I sort of touched on I sort of got to mention there's sort of a couple of ways that you can access these vocabularies there's a and I had the URLs on a previous screen um you can either do there's sort of a search interface so you can look at concepts one by one so you put in a like a keyword or something to discover it but I find that they have a have a list of all their their concepts in in one page and I find that that's a little bit easier to sort of tease out if that term if you're not quite sure what maybe they've used a different sort of name um of that instrument to what you expect um because you can sort of sort of move up and down move up and down this um this page and sort of look at things like title and and definition to sort of really check whether that that term is already in place in that vocabulary so basically checking the relevant vocabulary to check if it's currently already there if it's if it is there I then um reuse that term um but what is sort of the workflow if it's not present and basically um I will via email I actually submit the details of the new term that is required I provide just sort of some some information about the name of the instrument as I understand it but the next expectation that they may change this based on on on their current sort of naming protocols um I'll provide them with details such as a a web page with details about what the model and um further information is and this is actually quite a quick um process the turnaround that they're based in the UK so there is a bit of a time time difference there but it's in sort of in the order of days and then they'll email back with a confirmation of a new instrument code and name of that that that concept and then I can use that to to then um create terms um in my vocabulary so um as before um I'll use the BODC URL um we'll we'll we'll maintain that and because of that um for those that are familiar with um vocabularies within research vocabulary we do that in pool party and with the the need to retain the URL um we'll just read um import that new concept into the pool party vocabulary and then we'll reuse um and ensure that the match up with the name the definition and then like I said the the the people managing those vocabularies have always already done the hard work in terms of mapping to top concepts so um whilst um you know obviously it's a lot quicker if I was to sort of put it in straight away if the term was already there the the the turnaround and isn't too onerous so um and not you know you're not normally needing to get these new concepts in and you know new versions of vocabularies published really quickly so um just that sort of delay in things isn't isn't a concern for us so and obviously then um you know there are reasons in terms we're not having to worry too much about um governance of that that particular those concepts and the concepts within the larger vocabularies so um we find this quite a useful um process for us um and nothing too onerous so and that was all I had to say I did put a question slide there but as Rowan said I will um available for questions after Peter's talk so
