organization

The organization tab of the MatWerk workbook currently holds 56 rows. Every row follows the same shape, and that shape is the pattern below: a entity instance carrying the row's identity, denoted by value node nodes that hold its values, and object properties pointing at entities in other tabs.

Generated from the live sheet and MWO 3.0.1 by scripts/gen_patterns.py — regenerate it rather than editing it by hand.

The pattern

Drag the nodes, change the layout, or use Group to collapse a namespace. The picture is the example only; the declarations and annotations behind it are in module.ttl.

Columns

Column ROBOT Property Meaning
Label A rdfs:label label
Institution name I obo:IAO_0000235 denoted by
DE label A rdfs:label label
Acronym A nfdi:NFDI_0010015 has acronym
City I obo:RO_0001025 located in
Zip Code I obo:IAO_0000235 denoted by
country I obo:RO_0001025 located in
Institute Website I obo:IAO_0000235 denoted by
Parent organization I nfdi:NFDI_0000182
ROR ID I nfdi:NFDI_0001006

How to read it

  • The entity is typed obo:OBI_0000245 (organization) and carries only its identity, its label, and links.
  • A column marked I does not contain a value — it contains the label of another instance, which ROBOT resolves at build time. That is why every value node needs a unique label, and why a typo produces a silently missing relation rather than an error.
  • Columns marked A are literals on the entity itself.

Components (value nodes)

These value-node types live in the workbook's shared req_2 tab but belong to this pattern — they exist to describe it, and are counted by how often this tab references them.

Component Class References
institutional identification obo:IAO_0000303 56
country nfdi:NFDI_0000119 43
ROR identifier nfdi:NFDI_0001013 28
zone improvement plan code nfdi:NFDI_0001042 27

Query it

Retrieve instances of this pattern from the MatWerk Knowledge Graph (SPARQL endpoint):

SELECT ?x ?label WHERE { ?x a <http://purl.obolibrary.org/obo/OBI_0000245> ; <http://www.w3.org/2000/01/rdf-schema#label> ?label } LIMIT 10

The rows behind it are curated in the organization tab of the workbook.

Competency questions

The questions this pattern exists to answer. Each is answerable against the published graphs.

  1. Which organisations participate in NFDI-MatWerk?
  2. What is an organisation's ROR identifier, and in which city is it located?
  3. Which organisation is the parent of a given institute?
  4. Which researchers, instruments and facilities belong to a given organisation?

Field Value
Name organization
Submitted by the NFDI-MatWerk consortium
Also Known As the organization template tab of the NFDI-MatWerk workbook
Intent To represent a organization in the MatWerk Knowledge Graph: its identity, the value nodes that describe it, and its links to the other entities the NFDI-MatWerk consortium records.
Domains research data management; NFDI consortium structure
Competency Questions Which organisations participate in NFDI-MatWerk?; What is an organisation's ROR identifier, and in which city is it located?; Which organisation is the parent of a given institute?; Which researchers, instruments and facilities belong to a given organisation?
Solution description An entity individual typed obo:OBI_0000245 carries identity and label; each descriptive value is a separate value node individual reached by obo:IAO_0000235 (denoted by); links to other patterns are object properties onto those entities. Identity is a minted IRI msekg:<epoch_ms><counter>, so re-running the pipeline is idempotent.
Reusable OWL Building Block module.ttl — the example together with the axioms of every term it uses, extracted from the ontology, so the file stands alone
Consequences Values become reusable and independently addressable, and a value may be shared by many entities. The cost: every I reference resolves by label, so labels must be unique and a typo yields a silently missing relation rather than an error.
Scenarios “Max Planck Institute for Iron Research” is a organization, with institution name “Max Planck Institute for Iron Research_name_”; city “Dusseldorf”; zip code “40237”.

Formal characterisation

Measure Value
Consistency consistent — ROBOT 1.9.10, reasoner HermiT, merged with MWO 3.0.1
DL expressivity RRESTRCUCINTUNIVRESTREROIF — measured on the pattern together with a STAR module of exactly the terms it uses, so the figure describes this pattern rather than the whole ontology
Axioms / logical axioms 25 / 8
Classes / individuals 7 / 8

Consistency

pattern.ttl is checked against MWO 3.0.1 with ROBOT (--reasoner hermit) — the same reasoner process_spreadsheets runs over every generated module. A pattern that contradicts the ontology fails the documentation build.
