 Thanks everybody for turning up, Joel Ben here, business analyst in the services team. So the developers did a great job over six months of plug and play architecture that we can extend quite easily and quite quickly. One of the outcomes of that was really these plug and play widgets and services that we can offer through this developer toolbox and also going forward we can offer additional ones as open source tools that people can extend and also feedback into our repository as well. And the services themselves sort of expose a lot of the powerful components behind the registry and research data Australia to external developers. So these are things like searches and vocabulary services to pull information out of our vocabularies that have got published. Obviously external users can use them to tap into explore the Australian research data commons or research data of Australia and the services themselves are used in a lot of the case to underpin their hands widgets. So as I said before, if a developer has sort of hit the limits of a widget where they'd like to extend it, they can actually look at these services themselves and either extend the widget or build their own widgets by these services. These are quite well documented. The first service is the GetRivCS API and this is just a way to really get access to the contents of the collection through registry itself. Via the service you can perform quite complex searches of the registry to pull back specific records or records in a specific group based on specific subjects and things like that. Now this service itself pulls out RivCS XML. So it's useful to people that understand RivCS XML or using it in their own repository. It's also one of the uses is obviously to populate a pick list through a lookup service. So there may be again in a repository people are doing the relationships to RivCS to records and they can basically do a populated pick list of say collections or parties from a certain institution or all grants from a specific year or something similar to that. So again just the address research data australia.au. The web services themselves, they're not as pretty because there's no real fancy front end to them. There are little explanation diagrams for each, I think nearly all of the services that we have just showing sort of how they work. There's obviously the description and the use cases for each of the services, how people might want to implement them and the useful points about them. As you can see here before you start the one thing to note about the services themselves is that any developer that wants to use them actually has to register for a API key that they pass when they call them the services and that's just the way of us knowing and identifying who's actually using the services. You don't have to be a user with a log onto the registry. You can just click the link and it'll take you to a publicly accessible page where you fill out the organization, the contact email and why you want to basically use the API key and you click register and it will write there and then generate your key to pass with the service calls. In much the same way as the widgets, we have tables containing all the parameters that could be passed to the services themselves and again developers will understand that and if they don't they can get in contact via the community forum. In some of the services they're a little bit tricky. There's some FAQs or common questions about the services just to help out and a couple of example uses of working service calls and that's pretty much all I've got.
