Describes the time dimension of the data collection.

Specifies the type of summary statistic. Summary statistics are a single number representation of the characteristics of a set of values.

Indicates the statistical software package used in the production/processing/dissemination of the data. Data collection software is not covered in this list.

A typology of sampling methods.

Indicates the entity that provided the information carried by the variable.

Specifies the type of numeric data.

The procedure, technique, or mode of inquiry used to attain the data.

Specifies the event happening over the data life cycle that is considered significant enough to document.

Describes the level of proficiency of an individual in a natural language.

Describes the physical format(s) of the data documented in the logical product(s) of a study unit.

Specifies the type of date.

Identifies the type of data, which has a bearing on the acceptable data values, the operations that can be performed with the data, and the ways in which the data are stored.

Includes a typology of data sources.

A classification of contributor roles.

Describes the degree of similarity between two items or schemes (collections of items).

Standard set of characters upon which many character encodings are based (Wikipedia).

Describes the entity being analyzed in the study or variable. This vocabulary can also be used to describe the unit of observation, which is the unit being observed, or from which data are collected. The unit of observation can be the same as, or different from the unit of analysis.

Identifies the type of aggregation used to combine related categories, usually within a common branch of a hierarchy, to provide information at a broader level than the level at which detailed observations are taken. (From: The OECD Glossary of Statistical Terms)

The DCAT-AP conversion to a LinkML Schema is the intended point of truth for the DCAT-AP+ schema, but could be used alternatively as a LinkML representation of DCAT-AP for other Projects. It is a port of DCAT-AP to the LinkML world that is as faithful to the original as possible. This Persistent Identifier does not only provide the SHACL Shape, but could also be used as described [here](https://github.com/perma-id/w3id.org/tree/cecbc2e5f40d928f05ed5306d24fc60db0e7bb21/nfdi-de/dcat-ap-plus). DCAT-AP+ is a [LinkML](https://linkml.io/)-based extension of the [DCAT Application Profile 3.0](https://semiceu.github.io/DCAT-AP/releases/3.0.0/) that adds a provenance layer for describing how a dataset was generated and what it is about, using the [Starting Point Terms of PROV-O](https://www.w3.org/TR/prov-o/#description-starting-point-terms), the [QUDT ontology](https://www.qudt.org/), and [Dublin Core Terms](http://purl.org/dc/terms/).

DCAT-AP is a DCAT profile for sharing information about Catalogues containing Datasets and Data Services descriptions in Europe, under maintenance by the SEMIC action, Interoperable Europe. This Application Profile provides a minimal common basis within Europe to share Datasets and Data Services cross-border and cross-domain. [from homepage]

A metadata model for Dublin Core metadata

Metadata terms maintained by the Dublin Core Metadata Initiative, including properties, vocabulary encoding schemes, syntax encoding schemes, and classes. **Deprecation Notice**: While the `/elements/1.1/` namespace will be supported indefinitely, DCMI gently encourages use of the `/terms/` namespace (i.e., `dcterms`) ([source](https://www.dublincore.org/specifications/dublin-core/dcmi-terms/#section-3)).
