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 (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 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, 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.

 

1.1          Purpose

This document provides information to the NASA Earth Science community.  Distribution is unlimited.

 

1.2          Scope

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

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

  • Element Name: Specifies the element name.
  • Element Specification: Provides the sub-elements, cardinality of the sub-elements within (), any valid values within <>, applicable comments and notes within {}, 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:
  • Tags: Provides specific, related categorical values associated with this element, which are defined in Appendix A Tags Glossary.
  • Analysis: Provides additional information to provide clarity.
  • Sample Mapping/Mapping: Gives an XPath mapping for this element in DIF 9, DIF 10, ECHO 10, and ISO 19115-2 (MENDS) XML representations.  This can be considered as the "crosswalk" for this element.  For links to more information on XPaths please see the introduction's reference documents section.
  • Examples: XML snippets from cross-walked data formats documenting sample values for the element.

 

With the exception of Element Name each of the element's sections are that are included are listed in bold to make it easier for the reader to distinguish between the element's section headings and the descriptions.

There are three types of dates used in the UMM profiles:

  • Dates that concern the metadata record - called Metadata Dates in this document.
  • Dates that concern the resource itself (collections, etc.) - called Data Dates in this document.
  • Dates that describe the time period in which the data set was acquired - called Temporal Extent in this document.

 

Of these three date types this element is comprised of dates for when the metadata was created, last revised, planned for future review, or planned for deletion.  All of the dates use the ISO 8601 date and time conventions.  For dates related to the actual data or resource, the element Data Date should be used.  For dates that describe the acquisition period the Temporal Extent element should be used.

<Summary>
  <Abstract>The Lambert Glacier Basin (LGB) series of five oversnow traverses were conducted from 1989-95.  Ten metre depth (10 m) firn temperatures, as a proxy indicator of annual mean surface temperature at a site, were recorded approximately every 30 km along the 2014 km main traverse route from LGB00 (68.6543 S, 61.1201 E) near Mawson Station, to LGB72 (69.9209 S, 76.4933 E) near Davis Station.

10 m depth firn temperatures were recorded manually in field notebooks and the data transferred to spreadsheet files (MS Excel).

Summary data (30 km spatial resolution) can be obtained from CRC Research Note No.09 &amp;Surface Mass Balance and Snow Surface Properties from the Lambert Glacier Basin Traverses 1990-94&amp;.

This work was completed as part of ASAC projects 3 and 2216.

Some of this data have been stored in a very old format.  The majority of files have been updated to current formats, but some files (kaleidograph files in particular) were not able to be modified due to a lack of appropriate software.  However, these files are simply figures, and can be regernerated from the raw data (also provided).

The fields in this dataset are:

Latitutde
Longitude

Cane
Distance
Elevation
Density
Mass Accumulation

<Summary>
    <Abstract>The Atmospheric Infrared Sounder (AIRS) is a grating spectrometer (R = 1200) aboard the second Earth Observing System (EOS) polar-orbiting platform, EOS Aqua.  In combination with the Advanced Microwave Sounding Unit (AMSU) and the Humidity Sounder for Brazil (HSB), AIRS constitutes an innovative atmospheric sounding group of visible, infrared, and microwave sensors.  The AIRS Carbon Dioxide (CO2) Standard Retrieval Product consists of retrieved estimates of CO2, plus estimates of the errors associated with the retrieval.  In contrast to AIRX2RET, the horizontal resolution of this standard product is about 110 km (1x1 degree).  An AIRS granule has been set as 6 minutes of data, 15 footprints cross track by 22 lines along track.</Abstract>

2.2.8         Data Dates

Element Specification

DataDate/Date   (1)
DataDate/Type   (1)   <CREATE, UPDATE, DELETE, REVIEW>

 

Description

There are three types of dates used in the UMM profiles:

  • Dates that concern the metadata record - called Metadata Dates in this document.
  • Dates that concern the resource itself (collections , etc.) - called Data Dates in this document.
  • Dates that describe the time period in which the data set was acquired - called Temporal Extent in this document.

Of these three date types this element is comprised of dates for when the data or resource itself changed in some way.  It does not include the first or third bullets that describe Metadata Dates or Temporal Extent.  This element is made of two sub-elements, type and date.  The type describes what the date represents: a future review, when the resource was created, last updated, or planned for deletion.  The date describes when the resource had an action performed on it or when an action on it will occur as described by the type element.

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.

2.2.10     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.  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.

2.2.14     Collection Progress [R]

Element Specification

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

 

Description

Describes the production status of the dataset.  There are four valid 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.

<Quality>The dates provided in temporal coverage are approximate only.  Years are correct.

See the referenced paper for full details on steps taken to ensure quality of data.

To assess extraction efficiency for a range of sediment types, four marine sediments were analysed in detail.  Two international certified reference materials (CRMs) and two well-characterised Antarctic sediments were chosen to compare and contrast moderately to strongly contaminated samples (based on total metal digest), with clean samples of similar matrices.  One CRM was an uncontaminated continental shelf mud (MESS-2), and the other a contaminated harbour mud (PACS-2) (NRCC, 2002).  The two Antarctic sediments were collected as part of a regional hierarchical survey (Stark et al., 2003).  One Antarctic sample was from an area of known metal pollution in Brown Bay (BB), which is adjacent to the 'Old' Casey Station waste disposal site (Snape et al., 2001; Stark et al., 2003).  The second Antarctic sample was from a non-impacted control site from O'Brien Bay (OBB), 3 km south of Casey Station and the disposal site (Fig.  1).  The Antarctic samples, OBB and BB, have similar matrices, proportions of mud (less than 63 microns; 19% and 22% respectively) and total organic carbon contents (1.9% and 2.3% respectively).  Both MESS and PACS are sieved, homogenised and dried CRMs that have been ground to ~50 microns (NRCC, 2002).  In contrast, OBB and BB were only sieved to less than 2 mm, thereby removing only the very largest particles (less than or equal to 3%).  The Antarctic samples were collected using acid-washed PVC coring tubes.  The samples were kept frozen at -20 degrees C until wet-sieved with a small amount of clean filtered (0.45 microns cellulose nitrate) O'Brien Bay seawater through 2 mm nylon mesh held in a plastic sieve unit.  The sediments were then oven-dried to constant weight at 103 degrees C (Loring and Rantala 1992), and stored in Nalgene HDPE bottles until analysis.</Quality>

<Quality>Nucleic extraction blanks were carried out through amplification steps and sequence analysis quality control measures were followed on data analyzed.  Oceanographic instruments were calibrated at SeaBird before the cruise and sample blanks were periodically run for chlorophyll and nutrient analyses.</Quality>

Element Specification

AccessConstraints/Description   (1)

Description

The Description sub-element allows the author to provide information concerning accessing constraints.  This includes any special restrictions, legal prerequisites, limitations and/or warnings on obtaining the data.  Examples of values include: Public, In-house, Limited, and None.  The Value sub-element is used for special access control list (ACL) rules ( http://en.wikipedia.org/wiki/Access_control_list ) - for example, to hide metadata when it isn't ready for public consumption.  Providers use the AccessConstraint/Value element to specify various restriction levels with ACLs.  For example: A provider might specify a service Level ACL that hides all items (collections for this example) with a value element set to "15.0".  There is no controlled mapping for what the values represent.

Description

This entity stores the data's distinctive attributes (i.e.  attributes used to describe the unique characteristics of the resource which extend beyond those defined in this mapping).  AdditionalAttributes describe the data represented in each granule within a collection.  These values are important search criteria for the granules.  Example attributes include values for cloud cover, MODIS Tile grid coordinates, and elevation information.  All additional attribute definitions are included in the collection metadata.  A collection may also specify a value, to be understood as the value for all granules.  Granules reference defined additional attributes and supply a value that is associated to that granule.  Granules may not define a new additional attribute that is not defined by the collection.

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: https://gcmdservices.gsfc.nasa.gov/kms/concepts/concept_scheme/locations?format=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

Description

The Instrument element is nested within the Platform element and is used to register the device that measured or recorded the data, including direct human observation.  This is useful to find data from a specific instrument.  Note that the use of the "Sensor" object has been removed from UMM to avoid confusion between the names "Sensor" and "Instrument" as well as rationalizing the use of Instrument with the ISO Instrument representation.  To provide compatability with DIF 10 we map /DIF/Platform/Instrument/Sensor to Platform/Instrument/Instrument in UMM.  For ECHO 10, we also map Sensor objects to UMM Instrument objects.

 

The "ComposedOf" relationship shown above provides the ability for an instrument to be composed of one of more other instruments.  This hierarchical representation of Instrument composition provides the mechanism for modeling the complexity of modern instruments.  The nesting of instruments within an instrument is currently limited to 1 level and all instrument short names within a platform must be unique.

 

Significant changes in UMM Version 1.3

The use of the terms "Instrument" and "Sensor" has been a source of confusion and debate throughout the evolution of ESDIS metadata standards development.  GCMD's DIF standard used SensorName to represent an instrument.  ECHO-10 later attempted to model the complexity of modern instruments by creating an instrument object that can be composed of multiple sensors.  During the development of UMM, both approaches were supported by creating both Instrument and Sensor objects.  Beginning with Version 1.3 of UMM-Common, the Sensor object was removed in favor of using Instrument as the generalization of both Instrument and Sensor.  There was little semantic difference between the objects, so removing the Sensor class while retaining the ECHO-like relationships between instruments provides a rich structure for describing the instruments provided on a modern platform and eliminates the Sensor/Instrument debate for the entire CMR community.

 

The ECHO model of an Instrument that is composed of Sensors is implemented in UMM by using instrument composition.  Figure 2 below shows the relationships between the Acquisition Information, Platform and Instrument objects.  Note that the Instrument object now has a recursive relationship that is titled "ComposedOf".  This relationship enables a hierarchy of Instrument objects where each instrument can be composed of one or more other instruments.  This provides the capability to model complex instruments without resorting to a Sensor object.

Using the ECHO 10 example from below, a UMM-C representation written in JSON, as is implemented in the CMR, would look like the following:
