✨ SPARQLing NPs all over ✨

Why?

🌍 Because life on Earth is chemically wild, and most people never see it.

This bot showcases the hidden chemodiversity of nature — and how open data can make it visible.

It’s not just a daily curiosity — it’s an invitation.

🔬 If you see something that needs correcting, you can help improve wikidata.org/wiki/.

🧬 If you’re a researcher, this is a gateway into the LOTUS Initiative (lotus.nprod.net/)

10 Jahre #Hackday #Moers - zwei Tage mit voller inhaltlicher Druckbetankung, am zweiten Tag auch wieder verstärkt zu #OpenData und #LinkedOpenData #LOD während am ersten Tag noch #KI in der #Verwaltung (leider) dominierte (sich verstärkender Fachkräftemangel, chronische Unterfinanzierung, eher unattraktives Arbeitsumfeld und ungünstige Organisationskultur werden stochastische Papageien nicht nachhaltig kompensieren, sie lenken eher von den eigentlich zu ergreifenden Maßnahmen ab).

10 Jahre, die nicht spurlos vorbeigegangen sind (sofern man damals nicht als 13jähriger Teilnehmer eingestiegen ist).

Aufsteller mit Schriftzug "Hackday Niederrhein"
Stefan Kaufmann mit seinem kritischen Vortrag zu generativer KI und Plädoyer für mehr Linked Open Data stattdessen.

Done mapping all 40 #barangays of Luna, La Union, #Philippines 🇵🇭 in #OpenStreetMap, creating their #Wikidata items, and linking the two with each other.

A huge thanks to JR Dizon of the Luna Municipal Planning and Development Office for the boundary data. 🙏

Wanna play around? Here is the Overpass Turbo query: overpass-turbo.eu/s/21s0

And here is the Wikidata Query Service (WDQS) query: w.wiki/DfYz

Previously: en.osm.town/@seav/114092122864

Screenshot of an Overpass Turbo query result map showing the boundaries and the node label positions of the 40 barangays of Luna, La Union, with the relation of Nalvo Norte selected showing its tags.
Screenshot of the Wikidata Query Service query results showing a table of the 40 barangays of Luna, La Union, along with some of their properties such as population, coordinates, PSGC (Philippine Standard Geographic Code), and OpenStreetMap relation ID.
Screenshot of the Wikidata Query Service query results switched to the bubble chart visualization depicting the relative population sizes of the 40 barangays of Luna, La Union.

Florian Thiery @fthierygeo gives a talk on "Research Squirrel Engineers: How an independent RSE-driven network may help the NFDI" at #deRSE25 at @KIT_Karlsruhe which also tackles @NFDI #Base4NFDI - Basic Services for the NFDI topics on Research Software Engineering within the #RDM and #CAA_DE community of computational archaeology.

ZenodoResearch Squirrel Engineers - How an independent RSE-driven network may help the NFDIThe comprehensible/collaborative creation and FAIRification of research data is becoming increasingly important in the Citizen Science community to become part of an interdisciplinary knowledge graph and enrich the already interconnected data network with qualified data. Only in this way can this data be linked to other data and actively integrated into international initiatives (e.g. NFDI) and community hubs (e.g. Wikidata, FactGrid, Semantic Kompakkt, OpenStreetMap). Unfortunately, open-source (FOSS) research and FAIRification tools are often unavailable. However, these, in combination with Linked Open Data projects as demonstrators, can be created and curated by community and voluntary initiatives such as the Research Squirrel Engineers Network. This paper presents the Research Squirrel Engineers Network initiative, three research and FAIRification tools, and three Research Squirrels projects, as well as how Research Software Engineering may help make it even more helpful for the NFDI. These can serve as digital services for digital data management in archaeology and so be part of substantial interdisciplinary initiatives such as the NFDI. The paper, therefore, also presents the aims, benefits and implementation of the squirrel tools. The Research Squirrel Engineers Network (founded in 2019 to implement the SPARQL Unicorn) is a loose association of Linked Open Data/Wikidata enthusiasts, Research Software Engineers and Citizen Scientists focusing on computational archaeology, digital humanities and geoinformatics. The members develop and maintain research and FAIRification tools and implement them in concrete projects. A FAIRification tool for digital data management is the SPARQL Unicorn and its implementation for QGIS. The "SPARQLing Unicorn QGIS Plugin" allows sending linked data queries in (Geo)SPARQL to triple stores and prepares the results for the geo-community in QGIS. It currently offers three main functions: (A) Simplified querying of Semantic Web data sources, (B) Enrichment of geodata, and (C) Transformation of QGIS vector layers to RDF. In addition, the SPARQL Unicorn Ontology Documentation Tool enables the automated creation of HTML pages of Linked Open Data publications, e.g. via GitHub Action. One example are Irish Ogham sites on the Dingle Peninsula or data from Sophie C. Schmidt's dissertation project on "Brandenburg 5,000 BC" by converting a CIDOC CRM data model into Linked Open Data and visualising it as HTML with the help of SPARQL Unicorn. Another service is the "Fuzzy Spatial Locations Ontology", in which georeferencing's vagueness, uncertainties and ambiguities are made FAIR and comprehensible with the help of semantics and an ontology (based on PROV-O). An example of this is the modelling of sites of the eruption of the Campanian Ignimbrite in the Phlegraean Fields (39,940 yr b2k ± 150 years), which often correspond to archaeological sites, e.g. the Toplitsa Cave in Bulgaria. The "Squirrel Papers" complement the services to create a platform for publishing working papers, data, software, presentation slides and posters for citation. These services are accompanied by LOD / Wikidata / Open Street Map and Wikimedia Commons projects, such as Linked Open Ogham, Holy Wells in Ireland, or Linked Reindeers, where Scripts (primarily written in Python) help transform the tabular data into RDF or Quick Statements.
