1            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). These data are 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, 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 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, DIF 10, ECHO 10, EMS, ISO 19115-2:2009). The profile breaks down collections into elements or classes closely aligned to the ISO 19115-* Geographic Information Metadata schemas. Links to more information about the standards and specifications used in this document can be found in Related Documents section.

 

For each element, this document provides: 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.

 

1.1          Purpose

This document provides information to the National Aeronautics and Space Administration (NASA) Earth Science community. Distribution is unlimited.

 

1.2          Scope

This document describes the UMM Collection (UMM-C) model.

 

1.3          Impact

This document outlines a profile intended to be backward compatible with existing NASA Earth Science metadata implementations. It will impact providers from NASA Distributed Active Archive Centers (DAAC[s]), Common Metadata Repository (CMR) client developers, metadata catalog developers, and users.

1.7          Related Documentation

There is a document that fully describes metadata elements that are used in multiple models. This document, the UMM-Common (https://wiki.earthdata.nasa.gov/display/CMR/CMR+Documents) is documented separately. The Collection model makes multiple references to the UMM-Common throughout.

 

The ISO 19115-2 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 translation. The translation files can be found online at this site: https://cdn.earthdata.nasa.gov/iso/resources/transforms.   This translation   resulted from efforts of the group assembled for the Metadata Evolution for NASA Data Systems (MENDS).

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 identify the metadata record.

Analysis

The Metadata Management Tool (MMT) collection forms are organized based on the current UMM-C/UMM-Common metadata model. During MMT alpha and beta testing, some metadata providers indicated that they were confused by the Organization, Personnel and Party elements on the MMT collection record forms. Issues and areas of confusion included:

 

  • Roles:
    • pick lists   include roles that apply to organizations and roles that apply to individuals.
    • role values are not the same for DIF and for ECHO.
    • current   collection records in CMR have   non-standardized values for roles (including different variations of the same word (ARCHIVER, archive, archive data center), different   words for the same concept (PRODUCER,   PROCESSOR).
    • ECHO 10 records have Organization role built into field names (Processing Center, Archive Center) rather than as field values.
    • EDSC shows Processing Center and Archiving Center on Collection Information panel, but these are blank for DIF collections.
  • Contact Types:
    • contact type lists associated with organizations and personnel   are not   standardized.
    • contact type lists associated with organizations and personnel do not include 'modern' values.

 

Based on that feedback, we revisited the metadata model for these field groupings, giving consideration to how the metadata model can best reflect the physical model of organizations responsible for earth science datasets and people or groups who can be contacted with questions about those datasets. Based on this additional analysis, we are now recommending a collection metadata model which moves away from the Organization, Responsibility, and Party concepts, and moves back to the Data Center concept that better reflects the physical model of NASA DAACs and makes translation between GCMD collection record values and UMM-C values more straightforward and intuitive.

 

In addition, we are recommending changing the current UMM-C Personnel element to DataContact. The re-naming of this element emphasizes the function of a contact person, and the corresponding new role assigned to a DataContact better addresses whom to contact for answers to different types of dataset questions (e.g., TECHNICAL CONTACT, SCIENCE CONTACT, USER SERVICES, etc.)

 

A DataContact   may be associated with a DataCenter, as described in this element,   or   may be independent of a DataCenter, as described in the DataContact element.

2.2.9         DataContact

DataContact is a parent element to the ContactPerson and   the ContactGroup elements. Its purpose is to hold shared elements that its children will use. The DataContact element must exist with at least 1 of its children; it cannot exist on its own. Below is a diagram showing the relationships between the classes and their elements.  

 

The ContactPerson and the ContactGroup elements are described in detail in their respective sub-sections.

Figure 4 : Data Contact

 

Description:

This element includes metadata that describes who to contact to get information about the dataset. There may be zero to many contacts. A data contact can be either a ContactPerson or a ContactGroup.

 

Analysis:

As stated in the DataCenter analysis section the old UMM Personnel element was changed to the DataContact element group including its children of ContactPerson and ContactGroup. The DataContact element only holds shared sub-elements for its children elements and cannot be used on its own. Either ContactPerson or ContactGroup must be used. This change emphasizes the contact function and expertise of the person or group described. The corresponding new role assigned to DataContact gives a dataset user better information on whom to contact for answers to different types of dataset questions (e.g., TECHNICAL CONTACT, SCIENCE CONTACT, USER SERVICES, etc.)

 

A DataContact may be independent of a DataCenter. In that case, the NonDataCenterAffiliation field may be used to indicate the independent affiliation of the DataContact contact person or group.

2.2.13     Collection Progress [R]

Element Specification

CollectionProgress <PLANNED, ACTIVE, COMPLETE, NOT APPLICABLE, NOT PROVIDED>

 

Description

Describes the production status of the dataset. 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.

ACTIVE 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. Another example is when one version of a dataset is continuously collection data such as CERES EBAF-TOA Ed2.8.

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. Another example is when a legacy version of a product has been completed and no further updates will be made; such as with CERES EBAF-TOA Ed2.7.

NOT APPLICABLE use this entry only if this element is not applicable to the collection, such as a calibration collection.

NOT PROVIDED Do not use this value.   This value is needed by the CMR when translating older records that don't have a value for this element.   Once all the records provide a value, this value will be removed.

Description

This element is used to identify other metadata resources including but not limited to services, collections, visualizations, parameters, granules, documents, etc. that are associated with or dependent on the data described by the metadata. This element is also used to identify a parent metadata record if it exists.   This usage should be reserved for instances where a group of metadata records are subsets that can be better represented by one parent metadata record, which describes the entire set. In some instances, a child may point to more than one parent.

Recommendations

The MetadataAssociation should include a controlled Type attribute used to indicate the basis (justification) for relating one resource to another.   A unique identifier and authority should be added to formalize these associations.   In a future release we will add and merge the granule parent association mappings.   An association type code list needs to be created to use for the ISO 19115-1 translation.

Recommendations

During the UMM-C review, it was decided that the text inside this element must be deconstructed and the various components placed into the correct elements. If the metadata still retains a block of text in this element upon migration to the CMR, the text will be placed into the PublicationReference/OtherReferenceDetails element.

Analysis

Based on selected science keywords, the ISO Topic Category keywords should be auto-populated into the metadata by the CMR at ingest time. Metadata authors will also have the option to manually add/edit the ISOTopicCategory keywords in the metadata record using docBUILDER, Metadata Management Tool (MMT), or any alternate preferred XML editor.

2.6.4         Location Keywords

Element Specification

LocationKeywords

LocationKeywords/Category     (1)

LocationKeywords/Type     (0..1)

LocationKeywords/Subregion1     (0..1)

LocationKeywords/Subregion2     (0..1)

LocationKeywords/Subregion3     (0..1)

LocationKeywords/DetailedLocation     (0..1)

 

Description

This element specifies the name of a place on the Earth, within Earth's atmosphere, within Earth's magnetic field, or regions of the Sun. All of the sub-elements except for DetailedVariable are controlled and use the GCMD Location Keyword vocabulary. The vocabulary is managed by the Keyword Management System (KMS) and it can be found at this location: http://gcmdservices.gsfc.nasa.gov/static/kms/locations/locations.csv. The DetailedVariable is an uncontrolled free text element that allows the metadata author to include another location keyword to more fully describe the data.

 

When translating from specifications that use a single keyword such as ECHO 10, the value of the keyword is looked up in the KMS. The highest level hierarchy found that matches the value will be used to fill in the UMM hierarchy. For example there is an ECHO 10 collection record that contains:

<SpatialKeywords>
...
  <Keyword>Australia</Keyword>
...
</SpatialKeywords>

 

The keyword of Australia is looked up using the data of the KMS system. As of 10/13/2016 the top three values exist in the KMS that contain the keyword Australia plus I have added the last one for the purpose of this example:

"CONTINENT","AUSTRALIA/NEW ZEALAND","","","","02156a5c-5ea1-43e3-acf1-a89e99027555"

"CONTINENT","AUSTRALIA/NEW ZEALAND","AUSTRALIA","","","ce0984da-1151-41ff-8d92-ab551c9d08bc"

"CONTINENT","AUSTRALIA/NEW ZEALAND","NEW ZEALAND","","","d225920a-b027-4931-83d4-b60918251b59"

"CONTINENT","AUSTRALIA/NEW ZEALAND","AUSTRALIA","NEW SOUTH WALES","","xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"

 

The CMR will use the second one and fill in the higher elements in the UMM structure.   So the UMM record will look like the following:

LocationKeywords/Category = CONTINENT

LocationKeywords/Type = AUSTRALIA/NEW ZEALAND

LocationKeywords/Subregion1 = AUSTRALIA

Analysis

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.

Table 4 : Tags Glossary

Tag Name

Description

Required

This element is required.

Free Text Search

This element will be indexed by the CMR as part of the Free Text Search.

Search API

This element 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 parameters (or variables) that are part of a collection's science data.

Controlled Vocabulary

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

Markdown Support

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

Recommended

This element is recommended.

Validated Relationship

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

Normalize

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