Terms and abbreviations

Terms

application schema

conceptual schema for data required by one or more applications [iso_19101]

conversion rule

rule for converting instances in the input data structure to instances in the output data structure [iso_19118]

data interchange

delivery, receipt and interpretation of data [iso_19118]

data transfer

movement of data from one point to another over a medium [iso_19118]

NOTE Transfer of information implies transfer of data.

encoding

conversion of data into a series of codes [iso_19118]

encoding rule

identifiable collection of conversion rules that define the encoding for a particular data structure [iso_19118]

NOTE An encoding rule specifies the types of data to be converted as well as the syntax, structure and codes used in the resulting data structure.

transfer format

structured representation of data in a file for transfer between systems

NOTE Typically, a machine readable schema will document the structure of the data in the transfer file.

EXAMPLE GML [iso_19136] encodes the application schema in XML Schema.

simple feature

feature with all geometric attributes described piecewise by straight line or planar interpolation between sets of points [ogc_sf]

spatial data

data with a direct or indirect reference to a specific location or geographic area [inspire_directive]

spatial data set

identifiable collection of spatial data [inspire_directive]

spatial object

abstract representation of a real-world phenomenon related to a specific location or geographical area [inspire_directive]

Note
 It should be noted that the term has a different meaning in the ISO 19100 series. It is also synonymous with "(geographic) feature" as used in the ISO 19100 series.
spatial object type

classification of spatial objects [inspire_d25]

Note
 In the conceptual schema language UML a spatial object type will be described by a class with stereotype <<featureType>>.
transfer protocol

common set of rules for defining interactions between distributed systems [iso_19118]

Verbal forms for the expression of provisions

In accordance with the ISO rules for drafting, the following verbal forms shall be interpreted in the given way:

  • "shall" / "shall not": a requirement, mandatory for every data specification

  • "should" / "should not": a recommendation, but an alternative approach may be chosen for a specific case if there are reasons to do so

  • "may" / "need not": a permission

To make it easier to identify the mandatory requirements, the recommendations, and the permissions for INSPIRE data specifications in the text, they are highlighted and have an identifier.

Requirements are shown using this style.

Recommendations are shown using this style.

Permissions are shown using this style.

Specific notes are also highlighted. They do not have normative character.

Note
 This is a note.
