Introduction

 

Earth Observing System Data and Information System (EOSDIS) generates, archives, and distributes enormous amounts of Earth Science data via its Distributed Active Archive Centers (DAACs). This data is accessed and employed by a broad user community. It is therefore imperative that reliable, consistent, and high-quality metadata be maintained in order to enable accurate cataloging, discovery, accessibility, and interpretation. To increase the level of quality and consistency among its metadata holdings, EOSDIS has developed a model for various metadata concepts that it archives and maintains. This model aims to document vital elements that may be represented across various metadata formats and standards and unify them through core fields useful for data discovery and service invocations. This unified model, aptly named the Unified Metadata Model (UMM), has been developed as part of the EOSDIS Metadata Architecture Studies (MAS I and II) conducted between 2012 and 2013.

 

The UMM will be used by the Common Metadata Repository (CMR) and will drive search and retrieval of metadata cataloged within that system.

 

This document is intended to serve as a reference profile – a part of the UMM model - for geospatial science metadata for collections. This reference profile is referred to as the UMM-C, where ‘C’ indicates that this is the collection profile. The UMM-C attempts to unify several metadata specifications (DIF 9 [1] [2] , DIF 10 [3] , ECHO 10 [4] [5] , EMS, ISO 19115-2:2009 [6] , [7] , ISO 19115-1:2014 [8] ). The profile breaks down collections into elements or classes closely aligned to the ISO 19115-* Geographic Information Metadata schemas.

 

This document provides per element:  a description, analysis, and set of associated tags; specification of any conflicts that were identified by the unification process; and a discussion of applicable recommendations. The set of associated tags can be used to understand various aspects of the field. Some fields are identified as being part of a controlled vocabulary providing a uniform way of classifying and describing all EOSDIS metadata.  A reconciliation process will be developed to handle any conflicts specified by the unification process and the details will be developed on a provider-by-provider basis.

 

Feedback

Questions, comments and recommendations concerning this model should be directed to support@earthdata.nasa.gov

 

Metadata Profile Relationships & Related Documentation

 

Any collection instance governed by the UMM-C may have relationships to other metadata formats. As shown in Figure 1 , each collection may have child granules, associated collections, and may even include a parent collection that can serve as a discovery mechanism for closely related data products. In addition, each collection has a single instance of a “meta-metadata” profile, which has its own model, the UMM-M.  The meta-metadata model provides information about the metadata to which it is associated. Meta-metadata includes fields such as metadata quality assurance information, associated tags [9] , and metadata revision history.

 

Both the granule model (UMM-G) and the meta-metadata model (UMM-M) are documented separately. Additionally, the CMR Life Cycle, also documented separately, will govern this model and facilitate change.  These documents can be found at the following location: https://wiki.earthdata.nasa.gov/display/CMR/CMR+Documents.

 

Figure 1 - UMM-C Relationships

In addition, there is a document that fully described metadata elements that are used in multiple models. This document, the UMM-Common (https://wiki.earthdata.nasa.gov/display/CMR/CMR+Documents) is also documented separately. The Collection model makes multiple references to the UMM-Common throughout, as discussed in the following section: ‘Document Conventions’.

 

The ISO 19115-2 and ISO 19115-1 mapping paths and extracts of XML encoding of this standard used in this document are derived from the NASA Best Practices ISO translation from ECHO to 19115-2 and a similar ECHO to ISO 19115-1 translation. These translations [10] resulted from efforts of the group assembled for the Metadata Evolution for NASA Data Systems (MENDS) [11] .

 

Document Conventions

Each section of this document describes an element of the model and includes the following components:

 

  • Element Name: Specifies the element name.
  • Element Specification: Provides the sub-elements, cardinality of the sub-elements, and any other major factors that make up the element.
  • Description: Provides background information on the purpose of the element and its intended use.

Furthermore, any information about the element's current usage,   recommendations for usage, or unresolved issues is also documented here.

  • Cardinality: Indicates the expectation of counts for this element, summarized in Table 1:

Value

Description

1

Exactly one of this element is required

0..N

Optionally, up to and including N number of this element may be present

0..*

Optionally, any number of this element may be present

1..*

At least one of this element is required, any number may be present

 

 

Table 1 : Cardinality

 

 

Unified Modeling Language (UML) class diagrams and element lists are provided for each subcomponent of the model. The [R] after an element name indicates that the element is required.


Some elements are tagged as 'Required (with Option)'. These elements are similar to the xml scheme <choice> [13] element: one of the options is required, but there is a choice as to which option is applied. For more information about the various tags used throughout this document, refer to Appendix B: Tags Glossary.

 

As described in the Introduction, there is a UMM-Common document that contains elements and descriptions that are common to multiple UMM profiles. While UMM-C will refer to those elements and its details documented in UMM-Common, the UMM-C document takes precedence.  Any elements and/or details described in this document override the details found in the common document.  Examples of such scenarios include, but are not limited to: a sub-element cardinality difference - usually starting from a 0 or 1, additional sub-elements, sub-elements that should be excluded, additional analysis or recommendations, etc. As stated before the UMM documents can be found at the following location: https://wiki.earthdata.nasa.gov/display/CMR/CMR+Documents.

 

Collection Metadata Conceptual Model

 

As shown in Figure 2, the model has been organized into seven subsections that group related model elements. Each of these subsections and its constituent elements is documented individually.

Analysis

The metadata author or data center contact personnel determine the Entry ID for the GCMD DIF 9 specification. The Entry Id may be identical to identifiers used by the data provider's data center or organization. For ECHO 10 and DIF 10, the data providers supply both ShortName and Version of the product, which combined uniquely, identifies the metadata record. EMS has an element called Product provided by the data providers, which refers to a product identifier and is equivalent to the ShortName.

Collection Progress

Element Specification

CollectionProgress

 

Description

Describes the production status of the data set. There are three choices:
 

PLANNED refers to data sets to be collected in the future and are thus unavailable at the present time. For Example: The Hydro spacecraft has not been launched, but information on planned data sets may be available.

IN WORK refers to data sets currently in production or data that is continuously being collected or updated. For Example: data from the AIRS instrument on Aqua is being collected continuously.

COMPLETE refers to data sets in which no updates or further data collection will be made. For Example: Nimbus-7 SMMR data collection has been completed.

Description

This field stores the reference frame or system in which altitudes (elevations) are given. The information contains the datum name, distance units, and encoding method - which provide the definition for the system. This field also stores the characteristics of the reference frame or system from which depths are measured. The additional information in the field is geometry reference data etc.

 

Note: This field is currently underutilized in ECHO10 holdings. Out of over 4000 collections only 15 records include more information than <SpatialCoverageType>Horizontal</SpatialCoverageType>.

This class is found in both ECHO and GCMD.   It is controlled within GCMD but not controlled in ECHO.    GCMD's location is a hierarchical structure whereas in ECHO it is a single keyword.    GCMD's location hierarchies were primarily obtained from the following reference:
https://www.cia.gov/library/publications/the-world-factbook/ and it has since moved away from using the World Factbook in favor of the international standard ISO 3166-1.

Recommendations

Location data should be reconciled between both systems and controlled within the CMR through a keyword management system.

 

Additionally, this element should utilize controlled vocabulary and ISO 19115 keyword type codes documented at: https://github.com/ISO-TC211/XML/blob/master/standards.iso.org/19115/resources/Codelist/gml/MD_KeywordTypeCode.xml.

 

Specifically Spatial Keywords should use the “place” code as shown in examples.

Tag Name

Description

Required

This field is required.

Free Text Search

This field will be indexed by the CMR as part of the free text Free Text Search.

Search API

This field will be indexed by the CMR and will be exposed via the CMR. For example, the CMR will expose a "platform" search option, so the "Platform" element will have this tag. This is not to be confused with   variables that are part of a collection’s science data.

Controlled Vocabulary

This field will have a vocabulary that will be used to validate the value. This will most likely be done via a vocabulary management service.

Faceted

This field should be exposed by the CMR catalog via a faceted search response.

Markdown Support

This class supports markdown-formatted text. Additional information on markdown can be found at http://en.wikipedia.org/wiki/Markdown

Recommended

This field is recommended

Validated Relationship

Any associated granules use this field for validation against the collection, or associated collections are checked for validity

Normalize

The values contained in this field should be normalized (via enumerations or controlled vocabulary)

 

Tag usage is documented at the following wiki page:
