 a bunch of questions and as I think I'll ask one question myself and then I'll get into the Sligo questions and this is really for all of you just one thing that is a constant fascination is is how you support other organizations and individuals to build services or visualizations or whatever it might be you make use of the open data that you produce and and what you do yourselves and how much that's the core part of each of your sort of initiatives versus of letting people just put out there and letting people do what they will with it. Who wants to take that first? Sruti maybe? Sure. So I'd say like we do two main things. One I think because the the platform is open source it enables people to like see what already exists and we've already seen lots of examples of people building tools on top of it like we had like I mentioned there's like the R and Python API wrapper there's also a QA QC tool that makes it easy to check the quality of the data and so well like making it open source enables people from around around the world to be able to contribute and to kind of make it their own and the other thing that we try to do is through the workshops we the Ghana workshop that we did there were several people that had their organizations organization that was setting up their quality monitors around the country and we were able to kind of use the global community and network that we have to share the great work that they're doing and that was kind of how they got contacted by Colombia and we wrote an impact story about them recently which has also gotten some attention and there are a couple of other impact stories that will be coming out with over the course of the year to kind of showcase what people in the community are doing and help amplify the work that they're doing. Paul and Neil says a question to you I mean how much is supporting people to use your data and services at a core part of your work? Do you want to speak to that initially Neil? Yeah let me let me make one or two points and then I'll let you speak on that as well. In terms of people using the data there's a number of different levels at which we have to look at it. The first is just non-programmatic access which is actually something that a lot of lawyers need because they're only looking for four or five cases and very often there they'll just contact us and ask for help and we help where we can. With programmatic access there's a sort of more advanced access for people who know how to use APIs and have to consume them and over there the focus and how I've been building the APIs is really to try and make them as self-documenting as possible so that people can navigate them but very often again you get people who can only really work with an Excel sheet or a text export or something like that and so we do have to accommodate that as well and we try to as much as possible. I think the big sort of balance that we have to make is that again we're a foundational publisher we publish the source documents the original sources and we don't want to make predictions about what can and can't be done with that in a way that it restricts people in the tools that we make available and so I think the first priority is always making sure that the stuff is accessible and that if people have an idea that it might not be something that we anticipated that they are still able to do it and then beyond that we start engaging with organizations individually to see okay what are your specific needs and can we pull out something else for that. And just to add to that something that we've recently or rather africanly recently initiated is we have a constant surveying now on all of the sites which are partly a dip test to understand who are using the sites and what impact that it's having so that we can understand if the changes and additions that we make are having the impacts that we hope but also it means that we have a way of interrogating our user base in much more detail so we can learn from them better what tools or features we can add to the existing sites in order for them to be able to function more effectively and to be able to use the data that are available. Oh so you sound like a motorbike going by or maybe a moped just as you saw speaking Mark. Yeah so a question from David Newman just how usable are africanlees compared with equivalent commercial services. I mean we clearly have some bias in on this subject. I will make an initial comment and then let Neil follow up. One critically important thing that the leaves do and which is in the process of being rolled out is that they acknowledge the fact that not everyone has a stable or cost effective internet connection and actually more specifically it can be unusual to get an internet connection if you're sitting in a court of law so africanlea have created something. Neil can correct me if I'm wrong but uniquely to their service which the commercial providers don't have which is called pocket law which is the entire corpus of law on a thumb drive which then can update when the users get internet access and crucially for those people who are in slightly more remote areas or simply can't afford high bandwidth fees it means that they actually have a far superior product to the ones that are available to them from the commercial services but there's some other functionality things including citator that Neil can talk to more detail. Neil anything to add or? It's funny Paul should say what he did because I was thinking as well as a developer who's worked on the site perhaps I can't comment on how good it is but without this is an opportunity to see how great your work is. This is the path, this is a place for so what I will say with usability I'm well aware of the difficulty of using the commercial sites because I studied law myself and I had to use them for four years and it was a bit of a serious struggle. We take UX seriously it's not a tech box for us we do our testing and we bring in experts to have a look at usability and what we can do with that we have had some challenges on the main site we're now upgrading that to a new Drupal version and we've got in UX people again to look at the user flows and to test them to make sure people aren't getting stuck on the site and certainly on the citator as well we've done a lot of testing and there's ongoing feedback as Paul also mentioned the surveys on the sites to year where people are having trouble so we are resource constrained but as far as possible we're getting feedback and we take it very seriously that these things need to be usable especially as well since you know many of our users are like judges who are normally all the people and who prefer tables and faxes and pieces of paper and we have people as well who are experts at working with judges and their needs and what they're used to and we design for that as well. I just want to add a total example I had last year I had a meeting with the head of chambers of a large law firm in Johannesburg and I went in thinking he's never going to have heard of Safli and when I mentioned it his eyes brightened and said oh I use it every single day and literally picked up a case massive case file from his desk that had been printed out from a Safli even though he had access to all the commercial services he found easier and better for his needs in many circumstances than those commercial providers. So a couple of questions for Sfruti so Matt Stempik asked the best examples you've seen of citizens of South society using air quality data you may have covered some of that already and then there's a follow-up question as well just about how does air quality data collected by satellites compare with data collected by detectors on the ground so a couple of questions Sure um so yeah in terms of uh impacts or examples that we've seen um I mentioned the Ghana story there's also a workshop that we did in Sarajevo uh where uh because we bring together people from different sectors there was actually an activist and a local government official who um I think previously had been at odds with each other but like during the workshop kind of were able to find common ground and they actually drafted a community statement and were able to put together a plan and they presented it before before a parliament and they were able to kind of help start make some change the thing is you know as as we saw with the Beijing story you know having the data is like the first step and there is lots you can do with the the data um but actual um regulatory change takes a long time um and so uh like having the data and like being able to visualize it and share stories um and and like make and start that conversation is is uh is really important it's a good first step. What's your funding model I mean do you charge for access to the data in some circumstances or you fund it elsewhere what did you offer it yeah most of our funding comes in from grants we also have like certain partnerships uh where we work with organizations that are using the data but for the for the most part like the data is completely free and open for anybody to access yeah and uh sorry I just realized I didn't answer that follow-up question um so I am a software engineer I don't have enough of an atmospheric sciences background to answer that question um but I know that um uh like via satellites um you can get some obfuscation I guess uh due to like weather weather events but I think somebody with the uh like background would be able to answer that question better excellent so we're a little bit out of time there are a few questions still to ask but as as you probably heard we'll send questions down to each of the speakers if they want to do any follow-up thank you so much all of you that was a really fantastic session
