In ISO 19115-1:2014 "Geographic Information - Metadata - Part 1:Fundamentals" Standard, lineage is defined as provenance, source(s) and production process(es) used in producing a resource. According to the Commission Regulation (EC) No 1205/2008 of 3 December 2008 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards metadata, lineage means the history of a data set, and the life cycle from collection and acquisition through compilation and derivation to its current form, in accordance with EN ISO 19101.
Data quality have two facets to be considered: qualitative aspect and quantitative aspect. Quantitative facet expresses a numerical value as a result of the average quality. At ISO 19115 rule, this type of quality is known as Quality Reports. At them: Completeness, Consistency Logic, Positional Accuracy, Temporal Accuracy and Thematic Accuracy aspects, are evaluated. The qualitative aspect expresses the quality of data through the data sources and the processes performed to obtain the final product. The ISO 19115.Rule stablish the Lineage as the means for it.
In metadata, lineage includes free text about information about data sources and transformation steps followed in the creation process. Following INSPIRE Implementing Rules for Metadata, lineage is mandatory for datasets and dataset series, and it should include quality information for interoperability. It is not applicable to services.
Though the lineage is part of core metadata elements defined in ISO 19115, it is not always included and when it does exist, it is frequently incomplete or incorrect. This issue is avoiding real and professional use of the data sets. The presentation will focus in some real examples of lineage in European Data Sets and the impact in the real use.
