When using opensearch-client the user can specify a “property key”, one of the property keywords defined in the data model. In this case we are using the Earth Observation profile (EOP) model. opensearch-client allows the user to discover the keywords of the data model as the following query shows:
opensearch-client -m <datamodel_name>
For the EOP data model we have:
opensearch-client -m EOP
Resulting in:
Data model: EOP

Data model to handle Earth Observation dataset according to OGC® OpenSearch Extension for Earth Observation OGC 13 026
Metadata Id Metadata capability
=========== ===================
wkt Well Know Text geometry
title Title of the item (string)
enclosure Link to related resource that is potentially large in size and might
require special handling (RFC 4287). This metadata takes into
account the following data model parameters: enclosure:scheme,
enclosure:host
identifier Identifier name of the dataset within the collection
startdate Start time of the dataset (UTC ISO 8601)
enddate Start time of the dataset (UTC ISO 8601)
published Publication date of the item
updated Updated date of the item
related Link to resource related to the resource described by the containing
element. For example, slaves feed in an correlated search. This
metadata takes into account the following data model parameters:
related:title, related:type
self Link to resource that identifies a resource equivalent to the containing
element (RFC 4287).
productType A string identifying the entry type (e.g. GRD, SLC)
parentIdentifier A string identifying the parent of the entry in a hierarchy of resources
(e.g. ER02_SAR_IM__0P, MER_RR__1P, SM_SLC__1S,
GES_DISC_AIRH3STD_V005)
orbitNumber A number reprensenting the acquisition orbit
orbitDirection A string identifying the acquisition orbit direction. Possible values are:
ASCENDING, DESCENDING
track A number representing the acquisition orbit track
frame A number representing the acquisition orbit track
swathIdentifier A string representing the acquisition swath identifier
platform A string identifying the acquisition platform shortname.
operationalMode A string representing the acquisition sensor operational mode
polarisationChannels A string representing the acquisition polarisation channels
wrsLongitudeGrid A string representing the acquisition Wrs Longitude Grid
processingLevel A number representing the metadata processing level
To display the metadata, simply specify them separated by commas at then end of the query command.
