RedmerTomorrow I'll be learning all about data spaces and other types of data interop at #Semic2022 https://semic2022.eu/
See ya in Brussels! Or on the 🧵👇
Introduced by @DaveKeating, EU Commissioner Hahn is opening the conf.
- data spaces are key to an interoperable Europe.
- citizens can stay in control of their own data
The Czech presidency of the EU council now lets CIO Ondrej Profant present.
He emphasizes multilingualism in the EU, as there's often a tendency to use English. Semantic technologies could help that.
(It doesn't evade me that this thread is English, too)
EU DG DIGIT, Veronica Gaffey: Lack of interop between digital public services across sectors and EU countries
Cross-border interop should be embedded in the policy making.
Hilde Hardeman, DG EU publication office:
OP manages sets of conferent reference data: we make them, manage them, and update them.
That includes laws and regulations, but also code lists etc.
Keynote discussion: Building trust across the public & private sector between Klaus Ottradovetz (Atos) and David Scuderi (Amazon).
Moderator Leontina Sandu: From single strict specs, to interopable loosely combinable frameworks.
Q What do Amazon/Atos with data spaces. A Listen to our customers, so still very early for us.
Q What does the future bring for data spaces?
Ottradovetz: Gaia-X gives one way to describe services, to list and specify the ontology of a service, its entities.
Scuderi: semantic interop is a mission accelerator for smart city 360° insights.
Q Pitch two ideas to increase semantic interop and how can the EU level help?
Scuderi: One backwards looking: do not reinvent the wheel. That requires knowledge on prior art. One forwards looking: automation across semantics.
Ottradovetz: there is no comprehensive taxonomy on data spaces to begin with. Once we have such a model, we need a scalable platform to describe datasets.
Q How to connect the dots instead of bikeshedding?
Ottradovetz: The aforementioned a platform. And select baseline standards, protocols, and ontologies, just as we've converged on HTTP/DNS/HTML.
Scuderi: Tech interop was always the focus, here its about data. The EU is all working on the right things: i.a. IDSA (reference architecture?). Semantics of metadata is not enough, you'd still need to work on the actual data level. Key role for the Data Spaces Support Center as a convener.
After the first coffee of the day, it's time for Parallel Track I: Data exchange in and between sectors – the role for DCAT-AP
Speakers are from Ministry of Economic Affairs and Communication for Estonia, Digitaal Vlaanderen, Flanders, Belgium, DG SANTE, European Commission
First is Aas (EE), who emphasizes that a Data Portal facilitates the #FAIR principles (Findable, Accessible, Interoperable, Reusable) #opendata
Differentiates between high value datasets and regular datasets.
Somehow users find it useful when metadata in a catalogue is:
+ Valid
+ Accurate
+ Consistent
+ Complete
+ Timely
But DCAT-AP does not supply everything that a good data portal needs to have. So there's a national application profile, DCAT-AP-EE + vocabs, sector specs, metadata quality guidelines
Now on to the DCAT-AP backbone Datavindplaats from Flanders, by Nolf. #semic2022
There were many data catalogs: public data, non-public APIs, geodata.
Datavindplaats is the umbrella for finding all these datasets, with no domain-specific services. Integrating the previous three, by mapping previous metadata onto a common model = describe once.
As the GIS geospatial systems have been in used for quite a bit longer, both non-geospatial and geospatial need to be described in both systems and standards.
Findable at https://www.vlaanderen.be/datavindplaats #semic2022
Waiting for DCAT 3, for versions and dataset series.
Her last takeaway is that FAIR is not just enough. We need to make datasets lovable, too ❤️

Panel discussion on interoperability within & across sector specific data spaces: Cross domain use cases
DG Transport and DG Tourism have dataspaces, where inter-sector connections are desirable.
In tourism, a smooth UX truly helps the sector. Data integration, from train delay, bus stop, check-in time to "is there time to feed my child". #semic2022
The scale and opportunity, but also the challenges, for European dataspaces are huge. On the scale of electrification. But its a complex, subjective ecosystem, fundamentally decentralized.

Pierre-Antoine Champin, Data Strategist at W3C, mentions VSSO, an ontology on vehicle signals, adding semantic interop to an existing automotive VSS
VSSo: Vehicle Signal Specification Ontology
As the core ontology defined the structure, VSSo holds the vocabulary as defined by the standard catalogue. The main objective is, that VSSo doesn't diverege from the standard catalogue, so this is done automatically through tooling provided in the corresponding repository. The tooling takes the standard catalogue and maps it to concepts defined in the core ontology. The result is an OWL complient ontology, following the standard catalogue of VSS.
Time for project pitches! #semic2022
Budapest Tree Cadastre "FATAR" - Peter Gabor
> Automated 3d (point cloud) tree survey requires an ontology to describe the green infrastructure. Because it is instrumental in making Europe's 100 climate-neutral cities. #semic2022
Value of eDelivery to the dataspaces - Bogdan Dumitriu
> A standardized way to send data across data spaces. This minimizes creating data silos.
I've talked anout eDelivery and it sounds like a truly useful standard.
The Once-Only Technical System (OOTS): The French implementation plan - Jonathan J. Attia
> Once-Only is that institutions should reuse information, instead of re-registration of e.g. your personalia.
LEOS - Cristina Stanciulescu
> open source software for drafting and editing legislation using Akn4eu (Akoma Ntoso for EU).
Reusable semantic component prototype for interoperable e-Government: A case from Digital Europe for All (DE4A) - Karmen Kern Pipan, Head of Data Management Department, Ministry of Public Administration, Slovenia
Semantic Interoperability for Data Spaces - Vladimir Alexiev, Chief Data Architect, Ontotext
> data spaces aren't semantic enough: as the data in it (business payload) is not in the reference architecture IDSA necessarily semantic. Solid is the solution, also for EU (energy) sovereignty.
> data spaces aren't semantic enough: as the data in it (business payload) is not in the reference architecture IDSA necessarily semantic. Solid is the solution, also for EU (energy) sovereignty.
> we'll arrive faster at true data interoperability by not implementing a reference (UML) model in relational systems, but rather by modelling, linking our data as a semantic model
I found #SEMIC2022 to be successful. I've got to know some interesting projects, found the solution (Solid) to my project's problem, and talked with a lot of vendors.
