I need to provide information about the how observations were processed or models that were used to create the resource being described.

Overview


Tracking data sources and processing done to them is becoming increasing important as scientists seek to define trends and unexpected changes in the environment. Keeping track of data transformations and processing, generally termed lineage, is an important role of high-quality metadata. The ISO metadata standard provides a simple lineage model based on sources which are either used or produced in a series of process steps. This model can be helpful in many cases despite its simplicity. Sources and process steps are linked together to describe the lineage of a resource.

Recommendations


  1. Describe sources and process steps as separate objects and connect them with XML ids.

Conceptual Model


The ISO conceptual lineage model describes relationships between two basic types of objects: sources and process steps. This Figure shows an overview how sources and process steps are linked. Sources can be input to, or output (19115-2) from a process step. In this schematic, the first process step has two input sources and one output. That output is combined with the fourth source in the second step to produce the final source which is processed by the final step to create the product. Each process step has associated processing and algorithm information (also added in 19115-2). These improvements make it important to use 19115-2 if you need good lineage descriptions.

The second Figure shows more detail in the UML model used by the ISO Standard to describe lineage. In some cases, a simple descriptive statement can describe the lineage effectively. In more complex cases, multiple sources and process steps might be required. The definitions of sources and processSteps are also shown in the UML. The capability to specify the spatial and temporal extent of the source and to describe the rationale for a process step are new in the ISO Standard. Note that each source can have any number of associated sourceSteps and that each processStep can have any number of sources (and outputs in ISO 19115-2).

Note that ISO 19115-3 separates the lineage information from the data quality information so it appears directly under the MD_DataInformation object.

ISO Lineage Concepts and Connections

Implementation (XML)


Implementing these relationships in XML can seem daunting. It is accomplished in the XML representation using ids and references. The LE_Source and LE_ProcessStep objects (the boxes in the UML) are implemented as independent children of the LI_Lineage object with unique identifiers and the relationships, the source, output, and sourceStep roles in between the boxes, are implemented as references.

The example shown below shows an illustrative lineage section of a metadata record. The processing includes two processSteps, three external sources, and one intermediate Product.  Each source includes

  • an id (src_AVHRR_GAC, src_BR_CLIMATE, IP_1 and src_Land_Sea_Tag
  • a spatial and temporal extent , and
  • a sourceStep which is also defined by a reference to a full definition located in the first part of the lineage section (e.g. xlink:href="#ps_147").

The processing of each source is described in the first part of the lineage section. In this case, the process is the receipt of the the data by the archive. The processSteps include:

  • a brief description of the process
  • when it was done
  • who did it, defined by the processor,
  • a reference to the source that was processed (xlink:href="#src_BR_CLIMATE").

Note the use of id's within this record to identify sources and process steps and to make links between them.

        The CI_DateTypeCode is a codelist that the type of a date in the metadata.
        See http://standards.iso.org/iso/19115/resources/Codelist/cat/codelists.html for standard values.
        It includes two standard attributes: the codelist attribute gives a URL that gives the location of the codeList,
        and a value from the codelist. The location can be set to the standard location if the standard codelist is sufficient
        for the data provider needs or, if necessary, it can be set to a codelist that has been extended to include dataset
        specific values.
        The codeListValue attribute gives the value of the codelist. This is also the value of the element.
