The data set descriptor syntax is similar to the variable declaration/definition syntax of C and C++. A variable that is a member of one of the base type classes is declared by writing the class name followed by the variable name. The type constructor classes are declared using C’s brace notation. Enables description of atomic variables, arrays, structures, sequences, and grids. An Array is a one dimensional indexed data structure similar to those defined by ANSI C. Multidimensional arrays are defined as arrays of arrays. A structure groups variables so that the collection can be manipulated as a single item. The variables can be of any type. A sequence is an ordered set of N variables which has several instantiations (i.e. values). Variables in a sequence may be of different types. Each instance of a sequence is one instantiation of the variables. A grid is an association of an N dimensional array with N named vectors, each of which has the same number of elements as the corresponding dimension of the array. Each vector is used to map indices of one of the array’s dimensions to a set of values which are normally non-integral (e.g. floating point values). The N (map) vectors may be different types. Grids are similar to arrays, but add named dimensions and maps for each of those dimensions.", "datePublished": "2007-10-10","keywords": "data type description,data interchange,metadata", "license": [{"@type":"CreativeWork","name":"Distribution of this document is unlimited.", "identifier":"undefined"}], "version":"2", "audience": [{"@type":"Audience","audienceType":"Data Producers", "identifier":"http://cor.esipfed.org/ont/earthcube/AUT_0000001"},{"@type":"Audience","audienceType":"Data Users", "identifier":"http://cor.esipfed.org/ont/earthcube/AUT_0000002"},{"@type":"Audience","audienceType":"Data Facilities and Repositories", "identifier":"http://cor.esipfed.org/ont/earthcube/AUT_0000003"},{"@type":"Audience","audienceType":"Technologists", "identifier":"http://cor.esipfed.org/ont/earthcube/AUT_0000004"},{"@type":"Audience","audienceType":"Data Managers", "identifier":"http://cor.esipfed.org/ont/earthcube/AUT_0000005"},{"@type":"Audience","audienceType":"Developers", "identifier":"http://cor.esipfed.org/ont/earthcube/AUT_0000006"},{"@type":"Audience","audienceType":"Scientists", "identifier":"http://cor.esipfed.org/ont/earthcube/AUT_0000007"},{"@type":"Audience","audienceType":"Infomaticists", "identifier":"http://cor.esipfed.org/ont/earthcube/AUT_0000008"}], "about": [{"@type":"DefinedTerm","name":"Discipline-agnostic", "identifier":"http://cor.esipfed.org/ont/earthcube/ADO_0000188"}], "mainEntity":[{ "@type": "CreativeWork", "url": "http://cor.esipfed.org/ont/earthcube/ECRRO_0000208", "name": "Interchange file format" } ], "encodingFormat":["text/plain"], "additionalProperty": [{ "@type": "PropertyValue", "propertyID": "dc:BibliographicCitation", "name": "Bibligraphic citation", "value":"James Gallagher, Nathan Potter, Tom Sgouros, Steve Hankin, Glenn Flierl, 2007-10-10, The Data Access Protocol — DAP 2.0, ESE-RFC-004.1.1, accessed 2021-01-05, https://www.opendap.org/pdf/ESE-RFC-004v1.1.pdf" }, { "@type": "PropertyValue", "propertyID": "ecrro:ECRRO_0000138", "name": "has maturity state", "value": { "@type": "DefinedTerm", "name": "Used in multiple places", "identifier": "http://cor.esipfed.org/ont/earthcube/MTU_0000001" } }, { "@type": "PropertyValue", "propertyID": "ecrro:ECRRO_0000219", "name": "expected lifetime", "value": { "@type": "DefinedTerm", "name": "More than 5 years", "identifier": "http://cor.esipfed.org/ont/earthcube/ELT_0000002" } }, { "@type": "PropertyValue", "propertyID": "ecrro:ECRRO_0000600", "name": "primary publication", "value":"James Gallagher, Nathan Potter, Tom Sgouros, Steve Hankin, Glenn Flierl, 2007-10-10, The Data Access Protocol — DAP 2.0, ESE-RFC-004.1.1, accessed 2021-01-05, https://www.opendap.org/pdf/ESE-RFC-004v1.1.pdf" }, { "@type": "PropertyValue", "propertyID": "ecrro:ECRRO_0000218", "name": "Stewardship", "value": [{"@type":"Organization", "name":"OpenDAP", "url":"https://www.opendap.org/"}] }, { "@type": "PropertyValue", "propertyID": "ecrro:ECRRO_0000017", "name": "Usage", "value": { "@type": "DefinedTerm", "name": "Wide usage (>50 adopters)", "identifier": "http://cor.esipfed.org/ont/earthcube/UBA_0000001" } }, { "@type": "PropertyValue", "propertyID":"ecrro:ECRRO_0001301","name": "registration metadata", "value": { "@type": "StructuredValue", "additionalType": "ecrro:ECRRO_0000156", "contributor": { "@type": "Person", "name":"Stephen M.
