Flow information
Data set information
NameGeneral descriptive and specifying name of the flow.	Base nameGeneral descriptive name of the elementary, waste or product flow, for the latter including it's level of processing.; Sulfur dioxide
ClassificationOptional statistical or other classification of the data set. Typically also used for structuring LCA databases.	Class nameName of the class. / Hierarchy levelHierarchy level (1,2,...), if the categorization system is hierachical, otherwise emtpy or not used. Emissions to air / Non-renewable energy resources
CAS NumberChemical Abstract Systems Number of the substance. [Note: Should only be given for (virtually) pure substances, but NOT also for the main constituent of a material or product etc.]	007446-09-5
Sum formulaChemical sum formula of the substance.	SO2
Quantitative reference
Reference flow propertyOne of the Flow's Flow properties, which is set as the default flow property in which the flow measured. (Data set internal reference to one of the flow properties in section "Quantitative flow properties".)	Mass (kg)
Modelling and validation
LCI method
Type of flowNames the basic type of the flow.	Elementary flow
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").	2007-12-12T15:35:22+01:00
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.	ILCD format
Publication and ownership
UUID of flow data setAutomatically generated Universally Unique Identifier of this data set. Together with the "Data set version", the UUID uniquely identifies each data set.	f5227be8-9967-11da-a72b-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.it/elcd/flows/Sulfur_dioxide_Emissions_to_air_f5227be8-9967-11da-a72b-0800200c9a66_01.00.001.xml
Flow properties
Flow property"Flow property data set". Mean value (of flow property)Value for the flow expressed in this flow property in relationship to the the value of the flow expressed in its reference flow property (see field "Reference to reference flow property" in the "Quantitative reference" section). [Notes and examples: If the product flow "Diesel" is expressed by default in "Mass" (= reference flow property) and "kg" (= corresponding reference unit), the value that would be stated here for an additional flow property e.g. "Net calorific value" would be "42.5", as this flow property has the reference unit "MJ" and Diesel has a net calorific value of 42.5 MJ per 1 kg. It is recommended to report only significant digits of the value.] Minimum valueMinimum value of this flow property in case uncertainty distribution is uniform or triangular. Maximum valueMaximum value of this flow property in case uncertainty distribution is uniform or triangular. Uncertainty distribution typeDefines the kind of uncertainty distribution that is valid for this particular object or parameter. Relative StdDev in %The resulting overall uncertainty of the calculated variable value considering uncertainty of measurements, modelling, appropriateness etc. [Notes: For log-normal distribution the square of the geometric standard deviation (SDg^2) is stated. Mean value times SDg^2 equals the 97.5% value (= Maximum value), Mean value divided by SDg^2 equals the 2.5% value (= Minimum value). For normal distribution the doubled standard deviation value (2*SD) is entered. Mean value plus 2*SD equals 97.5% value (= Maximum value), Mean value minus 2*SD equals 2.5% value (= Minimum value). This data field remains empty when uniform or triangular uncertainty distribution is applied.] Data derivation type / statusIdentifies the way by which the Flow property value was derived (e.g. measured, estimated etc.), respectively the status and relevancy of missing data.
