Unit group data set: Units of length (en)
Unit group information
Data set information
Name of unit groupName of the unit group, typically indicating for which flow property or group of flow properties it is used. The individual units are named in the "Units" section of the "Unit group data set"	Units of length
ClassificationOptional statistical or other classification of the data set. Typically also used for structuring LCA databases.	Class nameName of the class. Technical unit groups
General commentFree text for general information about the data set. E.g. coverage of different unit systems, information sources used, etc.
Quantitative reference
Reference unitThe Unit group's unit in which the data set is expressed (data set internal reference).	m
Modelling and validation
Compliance declarations
Complianceone compliance declaration Compliance system name (source data set)"Source data set" of the "Compliance system" that is declared to be met by the data set. ILCD Data Network compliance Approval of overall complianceOfficial approval whether or not and in how far the data set meets all the requirements of the "Compliance system" refered to. This approval should be issued/confirmed by the owner of that compliance system, who is identified via the respective "Contact data set". Fully compliantMeets all requirements of this compliance aspect as defined in the respective "Compliance system".
Administrative information
Data entry by
Time stamp (last saved)Date and time stamp of data set generation, typically an automated entry ("last saved").
Data set format(s) (source data set)"Source data set" of the used version of the ILCD format. If additional data format fields have been integrated into the data set file, using the "namespace" option, the used format namespace(s) are to be given. This is the case if the data sets carries additional information as specified by other, particular LCA formats, e.g. of other database networks or LCA softwares.
Publication and ownership
UUID of unit group data setAutomatically generated Universally Unique Identifier of this data set. Together with the "Data set version", the UUID uniquely identifies each data set.	838aaa22-0117-11db-92e3-0800200c9a66
Data set versionVersion number of data set. First two digits refer to major updates, the second two digits to minor revisions and error corrections etc. The third three digits are intended for automatic and internal counting of versions during data set development. Together with the data set's UUID, the "Data set version" uniquely identifies each data set.	01.00.001
Permanent data set URIURI (i.e. an internet address) of the original of this data set. [Note: This equally globally unique identifier supports users and software tools to identify and retrieve the original version of a data set via the internet or to check for available updates. The URI must not represent an existing WWW address, but it should be unique and point to the data access point, e.g. by combining the data owner's www path with the data set's UUID, e.g. http://www.mycompany.com/lca/processes/50f12420-8855-12db-b606-0900210c9a66.]	http://lca.jrc.ec.europa.eu/lcainfohub/datasets/elcd/unitgroups/Units_of_length_838aaa22-0117-11db-92e3-0800200c9a66_01.00.001.xml
Units
Unit
Name of unitName of the individual unit.	m
Mean value (of unit)Mean value of this unit in relationship to the reference unit of this Unit group (see field "Reference unit" in the "Quantitative reference" section). [Notes and Examples: This vale is i.e. the linear conversion factor for this unit. E.g., if the Unit group would be "Units of mass" and the selected reference unit "kg", then the value stated here for an additional unit "g" would be 0.001, as 1 g is 0.001 times 1 kg. It is recommended to report only significant digits of the value.]	1.0
CommentGeneral comment on each single unit, typically giving the long name and unit system from which this unit stems, and (if necessary) referring to specifc data sources used, or for workflow purposes about status of "finalisation" of an entry etc.	meter
