00:09
Hey, hello, this I think this will be my last talk on this on this Conference so I have to enjoy it so so I'm talking here on behalf of Francois Brunier from titillers who's not able to join the conference unfortunately
00:27
Flora was here was a technical expert mostly on the on the client side Antonio and Juan was mostly on the back end. So so most of the team is actually here So if you have questions you go to them, so there's a typical thing with this logo
00:46
If you look at it from from this side, it was will tell you What will it say Good so a GN This is a thing that you have to see and then you never unsee it again
01:02
There's there's another thing with this logo It's it's a monk That didn't that makes a sign like this So those are those are the IDs of the designer behind this logo. We're considering to take a new logo
01:27
Although this one is very much appreciated, but we're still thinking about that so very short table of contents What's happening in June Network? I'm gonna throw a lot of topics on you
01:40
I probably don't have enough time to speak about everyone in detail But then we can have in the Q&A section more time to discuss it So short for those who are not who's not aware of G network So said I can do this really fast
02:02
Do your network? This is our website. It's a catalog free and open source. I wish your project founder is you don't take alert our bus At back then in the FAO It's adopted in numerous spatial data infrastructures and is Inspire ready and it has a growing community of users and developers of which you probably are
02:26
some So we share It's not handy that I'm looking like this because I wanted to talk to you probably I'm gonna stand here anyway
02:40
so the catalog is a way to share and organize the the spatial resources and It has a huge variety of metadata standards, which makes it kind of stand out between other catalogs This is our OS geo website, so we are an OS geo project since long
03:02
So that was the introduction to June Network it was pretty fast So what's happening in the community? Every year we have the Bolsona code sprint. I think we're on number 12 this year. So so We always invite all the OS geo projects there. But in practice it was is mostly the
03:21
Genome community joining up there Is it's a lovely code sprint in a lovely Italian monastery. So it's really Please join for example this year We discussed with with the tressress people the geo styler format that we discussed in some of the other
03:41
Talks Currently running is the OS geo Google Docs project and for for G another community. That's that's pulled by by Joe from Aston it's an amazing as effort from her so she's
04:00
setting up teams Engaging people we never met before and doing all kinds of Documentation efforts, that's it. That's a great value First results should come in the upcoming OS geo life It was a recently an elastic sprint which was actually at the second or third already where we are introducing
04:28
the current search index for elastic Elastic surge should improve the performance on on the larger catalogs and
04:40
Most importantly it will allow for clustering Because that's that's currently one of the big limitations of G network that is hard to cluster is possible we have some implementations, but it's it's not for the Average user but elastic search will will enable that Also
05:00
Sometimes we have limitations in the current search which would be really hard to implement in luching So with the last thing we will get that as a bonus so what what the Timeframe will be is a bit uncertain because it's a huge effort and and we're actually still looking for funding on that on that effort
05:24
But we hope that it will be next summer Looking a bit to flow out with the easy. It's not nodding yes or no, so we don't know So this is a thing I wanted to put in between it as Jew Jew cut we we currently offer a
05:42
Enterprise which is a commercial off-the-shelf product Which is the same code so it has the same GPL to license however We we release it a bit later than the community edition, and we offer longer support on that so so you have a
06:01
Three to five years support on that version This one can also be ordered as a hosted solution, so you have a kind of a One click Environment which is called yoga at life more on that on our booth, so this is a an interesting development
06:21
so the Flemish government developed a Geo DCAT app plugin That's so that's a DCAT is a is a format that is used in the open data community a lot however, it's it's kind of a challenge for G network because it's an RDF format and
06:41
You Know what is an XML oriented product and there isn't an XML encoding of RDF, but For example that doesn't have order where our XML world requires order in XML
07:00
in the in the properties So important in creating deacon geodica the app is quite simple and you network however importing it as JSON LD or turtle is it's kind of hard so that so we kind of made an intermediate wrapper that first converts
07:21
the RDF object into An XML object having a certain order so to your network is able to ingest that GDPR the the privacy regulation of the European Union even outside Europe you must have heard about it
07:46
One is used impacts on all of IT one of the mandates in that regulation was that that organizations have to set up a registry of data provenance and
08:01
Well logical choice would be to put that in an existing registry in your organization and the geo network could be one of those So we work with the Dutch National Health Institute to create a GDPR profile for geo network The GDPR model is quite quite similar
08:21
And there's things like title author that type of things But there's a couple of things that do not fit in the ISO model So we needed to create an extension on top of the ISO model, so we extended the schema but it has a so it was an amazing experience with those guys because also
08:41
When we started implementing that there was kind of also a return because they're there catalog was Growing considerably due to the effort and they had to go to all the departments to explain about GDPR and and their catalog so Also the efforts from them from the geo department were much clearer in the organization
09:04
So that was really a nice thing happening in parallel We're currently Investigating with a couple of our customers lightweight inspire harmonization
09:21
I've presented a couple of times on the on this topic on the inspire conference, but We see in a foot for those not here in Europe Organizations related to environment have to I comply to certain data models for their data and what we see is that that
09:43
People do that conversion to that European data model at the end of the pipeline So they work with their own models and then when all is done they do the conversion to the inspire model and This goes a bit against open data principles because you have to provide your data as primary and complete as possible
10:05
So that's why we're looking for alternative for this harmonization process and one of the things that we have Well, let me first do this this rule of thumb. So I always challenge organization saying okay, so you did this nice Transformation process, but now if I give you the inspire data set of your neighboring
10:26
municipality will you be able to ingest that go the other way and and put it next to your own data and use it in workflows and People then have to say, oh, I don't know about that. So
10:41
Our strongest advice the first advice we give is publish the inspire data in in in that transformed Format but also publish the original as is data. So people are always possible to go back to the originals Besides that we're suggesting
11:01
an RDF a type of approach where you tag your columns using the inspire ontology without touching the data and Let the consumers of the data do the actually harmonization step So so and and we're doing that based on the ISO 1 9 1 1 0 feature catalog
11:21
Standard so another thing this chemo.org Go and did the data crawlers. So we had a an interesting workshop at the JRC two months ago about catalogs and search engines and
11:42
Somebody from the your UK and geospatial Commission Presented that Their research at that found out that seventy five percent of the traffic to the catalog actually came from the search engine So if you want to promote Data and your catalog you have to make sure that your catalog is harvested by the search engines
12:04
and That's a that's a continuous effort to to Work on on search engine optimization for your catalog So in geo network 3.0. We added the capability to be crawled
12:21
But problems with spidering continued up to three six one which never released but you can you you could install it from git And that was partially related to the fact that there was low interest from from users as well as developers for this aspect and It's a bit of a shame
12:42
This is this is one of the tools that you can use to evaluate the this Crawling behavior of your catalog. This is the in this case the Google search console That gives you an indication of the coverage of your catalog how many records in your catalog are actually?
13:03
crawled by the spider and This this red line here is quite Flat because this is not Do you network was just but by geo API so I'm taking and by J API doesn't not have any errors usually in metadata you see a lot of errors like metadata or links in the metadata being invalid and
13:24
Then you see errors coming here Schema orc as you mark is a is a is a way to annotate your website So in search engines, so there's not just Google that that's all that being gandex is a wider initiative
13:42
Is able to extract structured content from that page for example addresses or opening hours of a shop? But they also have a schema or data set initiative, so if your website exposes Information about a data set and you tag it with this schema or data set annotations the search engine will be able to
14:04
Know that you're describing a data set So we always had the schema orc support As make micro data micro data is kind of a HTML way to do it However, this was replaced in 3-8 with a JSON LD type of approach
14:22
So we embed the JSON LD into the HTML and that's it's a bit more cleaner approach and was easier for us to to manage because schema orc has appeared to be quite fragile over time So If you have those those tags then then there's this initiative Google data set search that is able to
14:45
Find those data sets coming from the catalog So what's new in 3-8? 3-8 was actually launched last Monday So we actually was mostly Francois doing a lot of effort to finish it before this this conference, and it worked. I hope
15:06
There's not still too many blocking issues open that you're now confronted with else I'll suggest you wait till 3-8-1 It looks quite similar as 3-6 not not much changes on that side
15:23
But what is an important improvement is the workflow and draft so Antonio gave a presentation on this topic this morning So we have a You can now have a see a history of the of the all the edits and updates on your record and even
15:43
Jump back to a record in history if you're not happy with recent edits So if you're interested for this topic, please check out the video from from Antonio's presentation. That was really good presentation
16:04
Inspire meta data profile We're continuing to add improvements on that topic the thing is that also the validator is still in the kind of moving Goal that we try to
16:21
It so so that's a we're not finished with the with the metadata profile, but we're getting there For example, there was an improved anchor support. There is import vocabulary from inspire registry and Option to use a remote validator so you can use the inspire validator to validate metadata records
16:43
This is a this is a big one. So we had quite some discussion on the on the on the mailing list about this topic so up till 3.8. We have had ISO 1 9 1 3 9 as the default schema in in in G network but ISO 1 9 1 3 9 is 12 years old now the latest release and
17:04
It's a bit deprecated by ISO itself, but but in Europe is still quite common But we decided to remove it not remove it but Deprecate it. So so it's now Not the default schema anymore It's now ISO 1 9 1 1 5 dash 1 dash 3, whatever how you name it in the workshop
17:25
We we we we suggested to rename these standards and give them real names like tiger and lion Because that talks very much better ping-wing and Ginny pig But for now we still have this dash 1 and dash 3 and discussion
17:41
So in G network you have if you install it you have this schema by default ISO 1 I want to you know, I will still be available. No problem. If that's a relevant standard for you. It's one click to to Well, it's actually not a click but you load the templates of the proper schema that you want to have and it's there
18:05
We did some some patches on the on the 1 9 1 3 9 2 because Did ISO TC change some of their X paths of XML locations? so now that that's Fine again. Oh
18:23
That was it. I'm quite fast. No, thank you
18:47
It's really good to see that you're looking at including the new inspire validator service And hopefully that's in soon because otherwise I have to implement something for our portal
19:01
as part of that in Being able to call that service from within G network. Will you also provide an API? Version so we we could or our users could call that that validation through an API
19:22
So the ETF validator from inspire has an API that you can call well, yeah. Yeah. Yeah. Yes. I mean it's There's some discussions and some thoughts about whether Our NMA We had a service that called the European one and
19:44
Now we're looking to call the new ETF validator So the ETF project itself is also an open-source, yeah, I know the Dutch government implemented Deployed in their own ETF and applied their own rules in there That's that's what I've started looking at
20:00
But then I saw that if you if you guys are going to add that into G network Maybe I don't have to do so much Yeah Fantastic. Yeah, and and within that API you it's expected that metadata is in the catalog
20:20
We it doesn't it doesn't it is accept a remote Or a raw XML file. Yeah Okay This I think there is also a way to provide the XML at the end point, but I'm not sure I can do
20:42
No, I'll talk more with yeah with you as we go. Thank you Everybody happy. Okay Thank you, Paul. Look at their booth if you want to talk them
