Applicable Classes

Name Description Modifies Slot
Thing Root of the type hierarchy. Carries the identity and naming slots shared by every node that appears in a record's JSON-LD — the top-level resource and every nested object (Person, Organization, Place, Language, DefinedTerm, License, etc.). Modeled as its own class, not folded into CreativeWork, because those nested classes are Things but not CreativeWorks. no
ConformsTo A metadata standard/specification this resource's metadata conforms to (Schema.org, Bioschemas, Dublin Core, DCAT, ...). Standalone node typed as dcterms:Standard; deliberately NOT a Thing. no
ProvAgent A PROV-O agent (creator/author); id/name/url only. no
DataDownload A distribution of a dataset, modeled as an access point: the landing page is its dcat:accessURL (and schema:url). It does not link a direct file (no contentUrl/downloadURL), so it is deliberately not a schema:DataDownload. encodingFormat/mediaType describe the data available through it. Anonymous (no identifier) — projects as an inlined blank node (PropertyValue/Location precedent); the media-type IRI is a value (mediaType), not the node's identity. no
CreativeWork Shared base for every MIDAS resource type (Dataset, SoftwareApplication, DataCatalog, LearningResource, and the Collection subtypes). Every slice below inherits these slots; type-specific slots are added by the subtype classes in later slices. no
Language A language of the resource content: an ISO 639-2 code as name plus, when available, a Lexvo ISO 639-3 sameAs cross-link — both inherited from Thing (no additional slots). no
Agent A person or organization — used for creator. Concrete subclass is selected per node by agentType (curated is_person flag: true -> Person, otherwise Organization). no
Organization An organization — used for publisher, funder, and the MCC fallback creator. no
Person A person — used for dataset/software creators, with optional identifier (e.g. ORCID) strings; id/name inherited from Thing. no
Place A geographic place identified by its GeoNames Concept URI, dual-typed as schema:Place and geonames:Feature. Carries the GeoNames feature code and feature class. no
License A license governing the catalog metadata or source data. Emitted as a CreativeWork-typed node (per its @JsonldType) carrying name/url from Thing; no additional slots. no
DefinedTerm A controlled-vocabulary term (topic, biological scale, type-or-record, educational term, ...). It has a dual type set to the SKOS Concept type. The SKOS crosswalks below are INSTANCE-LEVEL — each term carries its own exactMatch/broadMatch IRI — which is exactly why they are slots on this class and NOT slot-level exact_/broad_mappings on the referring properties. (The source class carries a code comment stating the same.) no
DataCatalog A data catalog a resource is included in (the MIDAS Catalog or another). Common CreativeWork fields only; It is dual-typed (@type [schema:DataCatalog, dcat:Catalog]). no
RelatedData A related resource (publication, dataset, source page, related course), emitted as a CreativeWork-typed node. The kind of relationship is carried in its description; no slots beyond the inherited CreativeWork set. no
ComputerLanguage A programming language (software programmingLanguage / learning-resource programmingLanguage). name + sameAs from Thing; no additional slots. no
OperatingSystem An operating system the software runs on; id = the dbpedia resource IRI, name from Thing. (schema.org's OperatingSystem class — currently "new"/feedback area.) no
Dataset A dataset (type-or-record 1). no
SoftwareApplication A software application (type-or-record 2). rights is inherited from CreativeWork. no
Dashboard A dashboard (type-or-record 6). Emits as schema:SoftwareApplication with applicationCategory="Dashboard" set at runtime; no additional slots. no
Repository A repository (type-or-record 7): a specialized DataCatalog. Emits as dual-typed via inheritance. no
Literature A literature collection (type-or-record 8). Emits as schema:Collection. no
ModelingStudy A modeling-studies collection (type-or-record 9): Literature with genre="modeling studies"; no additional slots. no
DiseaseSpecificCollection A disease-specific collection (type-or-record 10): Literature with genre="disease-specific collection"; no additional slots. no
LearningResource An educational resource (type-or-record 16). no
Course A course (educational resource with course=true); adds a course instance. no
CourseInstance An offering/instance of a Course. Extends Thing (consistent with Person/Place/Language). courseMode carries an IRI when the mode has one, else the mode name. no
