RINF data quality & submission
Audits of your RINF data with SHACL checks that go beyond ERA's own validation, hands-on support for your submissions, and training in the ERA ontology and SPARQL.

Services around my tools
RINF Atlas and MatGUI are open source and free to use. When you need them on your own infrastructure, tailored to your data or backed by support, MatData builds and runs it for you.
RINF Atlas
The map and search stay free and open. For infrastructure managers, railway undertakings and ministries that need more from ERA's Register of Infrastructure, MatData offers:
Your own private instance
RINF Atlas on your own infrastructure, behind your single sign-on, with your own layers on top: asset data, possessions, planned works. Set up, supported and backed by an SLA.
Custom facets & analyses
Tailored views built on the editable SHACL facets, such as route compatibility for your rolling stock fleet or ETCS and ERTMS coverage. Delivered as fixed-price projects.
Premium features
Saved searches, change alerts ("tell me when line X changes"), dataset diff reports, bulk API access and branded PDF or Excel exports, on top of the free core.
Data products
Cleaned and derived datasets, such as merged track geometries, a routable network graph and ready-to-use GIS packages, or a commercial API. Built on ERA's open RINF data (CC BY 4.0), with attribution.
MatGUI
MatGUI is free to use as a website, on npm and on Docker Hub. When your team works with SPARQL every day, MatData can shape it around your organisation:
Your own private instance
Hosted by MatData or on your own infrastructure, behind your company login (OAuth or OpenID Connect, such as Microsoft Entra ID), with your branding and default settings.
Endpoint shortcuts & saved queries
A shared catalogue of your SPARQL endpoints and a library of saved, named queries, so nobody has to paste URLs or rewrite the same query twice.
Queries stored in your own triple store
Saved queries kept as RDF on a SPARQL endpoint you control, so they stay versioned, searchable and shared across teams and tools.
Query forms & dashboards
Parameterised queries turned into simple forms, tables and charts, so colleagues who don't write SPARQL can still get answers from the knowledge graph.
Integration & embedding
MatGUI embedded in your portal, data catalogue or intranet, and connected to secured triple stores such as GraphDB, Stardog, Virtuoso or Amazon Neptune.
Features on request
New views, plugins and workflows built to your specification and contributed back to the open-source project, plus SPARQL training and support for your team.
The same for my other tools
MatData offers similar services for the other open-source tools on GitHub: private instances, tailoring to your data, features on request, support and training.
shacl-report
Validates RDF with SHACL and turns the report into a table people can read, with the shapes behind it and their rules runnable as SPARQL.
rdf-compare
A fast CLI that computes the difference between two RDF files, blank nodes included, with a CI mode for data pipelines.
Ontology Explorer
Browse an ontology's classes, properties and their relations, so modellers and developers find their way around it quickly.
RDF Data Manager
Create, read, update and delete RDF data behind a SPARQL endpoint, with forms driven entirely by SHACL shapes.
