MEx Metadata Schema

The MEx metadata schema is used to catalog Public Health data, resources and activities of the Robert Koch Institute (RKI) - the federal Public Health institute of Germany - with the goal of making them findable and accessible via a web application.

The MEx metadata schema enables the description of data and resources derived from the research and other activities of the RKI. In most cases, the RKI’s public health data are protected by data protection laws. Instead of publishing the data itself, MEx provides descriptions about the data. The MEx metadata model is designed to provide comprehensive descriptions for RKI’s public health data. MEx users can both find and assess whether the data matches their interests and needs. To achieve this, we provide detailed information about the data in the form of variables. Variables describe how the actual data is specified and form the basis for a data-based evaluation of studies, for example.

To collect information, MEx uses a mixed approach: In addition to manually compiling, we also automatically extract information from various primary sources managed by the RKI departments. To model this, we rely on the W3C recommendations DCAT and PROV-O.

hadPrimarySource	A primary source for a topic refers to something produced by some agent with direct experience and knowledge about the topic, at the time of the topic’s study, without benefit from hindsight. Because of the directness of primary sources, they ‘speak for themselves’ in ways that cannot be captured through the filter of secondary sources. As such, it is important for secondary sources to reference those primary sources from which they were derived, so that their reliability can be investigated. A primary source relation is a particular case of derivation of secondary materials from their primary sources. It is recognized that the determination of primary sources can be up to interpretation, and should be done according to conventions accepted within the application’s domain ([PROV-O, 2013-04-30 ](http://www.w3.org/TR/2013/REC-prov-o-20130430/)).

Organization

https://mex.rki.de/schema/entities/organization
Represents a collection of people organized together into a community or other social, commercial or political structure. The group has some common purpose or reason for existence which goes beyond the set of people belonging to it and can act as an Agent. Organizations are often decomposable into hierarchical structures ([The Organization Ontology, 2014-01-16](http://www.w3.org/TR/2014/REC-vocab-org-20140116/)).

hadPrimarySource	A primary source for a topic refers to something produced by some agent with direct experience and knowledge about the topic, at the time of the topic’s study, without benefit from hindsight. Because of the directness of primary sources, they ‘speak for themselves’ in ways that cannot be captured through the filter of secondary sources. As such, it is important for secondary sources to reference those primary sources from which they were derived, so that their reliability can be investigated. A primary source relation is a particular case of derivation of secondary materials from their primary sources. It is recognized that the determination of primary sources can be up to interpretation, and should be done according to conventions accepted within the application’s domain ([PROV-O, 2013-04-30 ](http://www.w3.org/TR/2013/REC-prov-o-20130430/)).

Variable Group

https://mex.rki.de/schema/entities/variable-group
The grouping of variables according to a certain aspect, e.g. how the information is modelled in the primary source.

	type	array
	items	Resource
	minItems	1
hadPrimarySource	A primary source for a topic refers to something produced by some agent with direct experience and knowledge about the topic, at the time of the topic’s study, without benefit from hindsight. Because of the directness of primary sources, they ‘speak for themselves’ in ways that cannot be captured through the filter of secondary sources. As such, it is important for secondary sources to reference those primary sources from which they were derived, so that their reliability can be investigated. A primary source relation is a particular case of derivation of secondary materials from their primary sources. It is recognized that the determination of primary sources can be up to interpretation, and should be done according to conventions accepted within the application’s domain ([PROV-O, 2013-04-30 ](http://www.w3.org/TR/2013/REC-prov-o-20130430/)).

Variable

https://mex.rki.de/schema/entities/variable
Variables are defined for the data-based evaluation of investigations (e.g. studies). A variable is characterized by its data type (e.g. integer, string, date) and value range. The variable can be either quantitative or qualitative, i.e. the value range can take numerical or categorical values.
type	object

belongsTo	The variable group, the described variable is part of. Used to group variables together, depending on how they are structured in the primary source.
