Dataset
	a dataset describes LCI related information of a unit process or a terminated system comprising metaInformation (description of the process) and flowData (quantified inputs and outputs and allocation factors, if any).
Meta information
	meta information contains information about the process (its name, (functional) unit, classification, technology, geography, time, etc.), about modelling assumptions and validation details and about dataset administration (version number, kind of dataset, language).
Process information
	Contains content-related metainformation for the unit process.
Reference function
	Contains the identifying information of a dataset including name (english and german), unit, classification (category, subCategory), etc..
Name	SpoldID	Type	Size	Options	Multiple occurences	Required
datasetRelatesToProduct	400	Yes/No	1	-	No	Yes
	Indicates whether the dataset relates to a process/service or not.
	In the ecoinvent quality network the value required is 'yes' for unit processes and multioutput processes and 'no' for elementary flows and impact categories.
name	401	Text	80	-	No	Yes
	Name of the unit process, elementary flow or impact category.
	For unit processes and system terminated name is used as the identifying entry together with unit, location and infrastructureProcess (yes/no). The process name is structured as follows (quality guidelines of ecoinvent 2000): 1. Name of product/service, production process or worked product, level of processing; 2. additional descriptions, separated by comma: sum formula, site of production or provenience, company, imports included or not; 3. Location in the value added chain (at plant, at regional storehouse), or destination (for wastes: to sanitary landfill, to municipal incineration) always using "at" and "to", respectively.
	For elementary flows name, unit, category and subCategory are used as the discriminating elements. The nomenclature of the SETAC WG 'Data quality and data availability' is used for elementary flows as far as possible.
	For impact categories, name, location, unit, category and subCategory are used as discriminating elements. The naming of impact categories takes pattern from the corresponding original publication.
	English is the default language in the ecoinvent quality network.
localName	490	Text	80	-	No	Yes
	see 'name' for explanations.
	German is the default local language in the ecoinvent quality network.
infrastructureProcess	493	Yes/No	1	-	No	Yes
	Indicates whether the process is an investment or an operation process. Investment processes are for instance building of a nuclear power plant, a road, docks, construction of production machinery which deliver as the output a nuclear power plant, a km road, one seaport, and production machinery respectively. It is used as a discriminating element for the identification of processes.
	Not applicable for elementary flows and impact categories.
amount	404	Number (Real)	s.n.	-	No	Yes
	Indicates the amount of reference flow (product/service, elementary flow, impact category).

	For elementary flows it is the unit in which exhanges are reported.
	For impact categories, it is the unit in which characterisation, damage or weighting factors are expressed.
	SI-units are preferred. The units are always expressed in English language.
category	495	Text	40	-	No	Yes
	Category is used to structure the content of the database (together with SubCategory). It is not required for the identification of a process (processes in different categories/subCategories may therefore not be named identically).

	English is the default language in the ecoinvent quality network.
subCategory	496	Text	40	-	No	Yes
	SubCategory is used to further structure the content of the database (together with category). It is not required for the identification of a process (processes in different categories/subCategories may therefore not be named identically).

	For lognormal distribution the square of the geometric standard deviation (SDg^2) is entered. SDg^2 is dimensionless. MeanValue times SDg^2 equals the 97.5% value (=maxValue), meanvalue divided by SDg^2 equals the 2.5% value (=minValue).
	For normal distribution the double standard deviation (2*SD) is entered. 2*SD is given in the same unit like the meanValue. MeanValue plus 2*SD equals 97.5% value (=maxValue), meanValue minus 2*SD equals 2.5% value (=minValue).
	This data field remains empty when uniform or triangular uncertainty distribution is applied (uncertaintyType = 3 and 4, respectively).
formula	3711	Text	40	-	Yes	No
	Chemical formula (e.g. sum formula) may be entered. No graphs are allowed to represent chemical formulas.
referenceToSource	3715	Number	3	Reference to 801	Yes	No
	An ID used in the area 'sources' of the respective dataset is required. It indicates the publication (of the ecoinvent quality network) where the unit process raw data at issue and the characterisation, damage or weighting factors of an impact category, respectively, are documented.
pageNumbers	3716	Text	30	-	Yes	No
	The page numbers of the publication (of the ecoinvent quality network) where the exchanges of the unit process at issue are documented.
generalComment	3792	Text	32000	-	Yes	No
	A general comment can be made about each individual exchange (or characterisation, damage or weighting factor) of a particular unit process and impact category, respectively.
	It contains the string of code numbers of the ecoinvent uncertainty assessment (if pedigree matrix is applied) as well as further comments about the uncertainty assessment.
	The string of numbers of the uncertainty assessment describes (reliability, completeness, temporal correlation, geographical correlation, further technical correlation, sample size) and uses a score from 1 to 5. See methodology report for further information.
localName	3794	Text	80	-	Yes	No
	Name of the exchange (or characterisation, damage or weighting factor) of a particular unit process and impact category, respectively (in German local language).
infrastructureProcess	3508	Yes/No	1	-	-	Yes, if 3503=5
	Describes whether the intermediate product flow from or to the unit process is an infrastructure process or not.
	Not applicable to elementary flows.
minValue	3795	Number (Single)	s.n.	If UncertaintyType=triangular/ uniform	Yes	No
	Contains the minimum value for exchange data with a uniform or triangular distribution.
	In case of LCI results imported into the ecoinvent database, the 2.5% value is reported in this field.
maxValue	3796	Number (Single)	s.n.	If UncertaintyType=triangular/ uniform	Yes	No
	Contains the maximum value for exchange data with a uniform or triangular distribution.
	In case of LCI results imported into the ecoinvent database, the 97.5% value is reported in this field.
mostLikelyValue	3797	Number (Single)	s.n.	If UncertaintyType=triangular	Yes	No
	In some cases the MostLikelyValue is available for exhange data with triangular distribution. However, do not use this field, but calculate the mean value, (minValue + mostLikelyValue +maxValue)/3, and enter it into the field "meanValue").
inputGroup	3503	Number	1	1=Materials/Fuels, 2=Electricity/Heat, 3=Services, 4=FromNature, 5=FromTechnosphere	Yes	Yes
	Indicates the kind of input flow. The codes are: 1=Materials/Fuels, 2=Electricity/Heat, 3=Services, 4=FromNature, 5=FromTechnosphere.
	Within the ecoinvent quality network, only 4 and 5 are actively used (any material, fuel, electricity, heat or service is classified as an input from technosphere).
outputGroup	3504	Number	1	0=ReferenceProduct, 1=Include avoided product system, 2=Allocated by product, 3=WasteToTreatment, 4=ToNature	Yes	Yes
	Indicates the kind of output flow. The codes are: 0=ReferenceProduct, 1=Include avoided product system, 2=Allocated by product, 3=WasteToTreatment, 4=ToNature.
	The options 0, 2, and 4 are actively used in the ecoinvent quality network.
	Products of multioutput processes are classified as allocated by-products (2).
	Avoided product systems are modelled with a negative input from technosphere. WasteToTreatment are modelled like services (hence inputFromTechnosphere). Therefore codes '1' and '3' are not required.
Allocation
	Contains all information about allocation procedure, allocation parameters and allocation factors applied on a multi-output process.
Name	SpoldID	Type	Size	Options	Multiple occurences	Required
referenceToCoProduct	2401	Number	10	Reference to internal TIndexNumber	Yes	Yes
	Indicates the co-product output for which a particular allocation factor is valid. Additional information is required about the exchange on which the allocation factor is applied (see 'referenceToInputOutput').
	MultipleOccurences=Yes is only valid, if referenceFunction describes a multioutput process.
allocationMethod	2403	Number (Byte)	2	-1=Undefined (default)0=Physical causality1=Economic causality2=Other method	Yes	Yes
	Indicates the kind of allocation parameter chosen. The codes are: -1=Undefined (default). 0=Physical causality. 1=Economic causality. 2=Other method. 'Other method' comprises in particular physical parameters (like mass, energy, exergy, etc.) and parameters other than economic.
	MultipleOccurences=Yes only valid, if referenceFunction describes a multioutput process.
fraction	2404	Number (Decimal)	-	-	Yes	Yes
	Allocation factor, expressed as a fraction (in %), applied on one particular exchange for one particular co-product. The sum of the allocation factors applied on one particular exchange must add up to 100%.
	MultipleOccurences=Yes only valid, if referenceFunction describes a multioutput process.
explanations	2407	Text	32000	-	Yes	No
	Contains further information about the allocation procedure and the allocation parameter chosen. An eventual coincidence in allocation factors when comparing different allocation parameters (like physical and economic ones) may be reported here as well.
referenceToInputOutput	2492	Number	10	Reference to internal TIndexNumber	Yes, multiple per Allocation	Yes
	The data field is only required, if the reference function describes a multioutput process.
	Lists the relation(s) to which a certain allocation factor is applied.
	MultipleOccurrence=Yes on two levels: Firstly, the reference occurs per co-product and secondly, the reference occurs per input and output flows which are allocated to the co-products.
