cmr.sample-data

Sample Data for the open source NASA Common Metadata Repository (CMR)

About the CMR

The Common Metadata Repository (CMR) is a high-performance, high-quality, continuously evolving metadata system that catalogs all data and service metadata records for the EOSDIS system and will be the authoritative management system for all EOSDIS metadata. These metadata records are registered, modified, discovered, and accessed through programmatic interfaces leveraging standard protocols and APIs.

Usage

Start the REPL:

$ lein repl

Sample data files have two general result types: they may either be returned as a file object or as the data stored in the file:

[cmr.sample-data.dev] λ=> (data/get-ges-disc-provider :obj)
#object[java.net.URL 0x6717aefa
  "file:/alt/home/oubiwann/lab/NASA/CMR/cmr-sample-data/resources/data/providers/GES_DISC.json"]
[cmr.sample-data.dev] λ=> (data/get-ges-disc-provider :data)
"{\n  \"provider-id\": \"GES_DISC\",\n  \"short-name\": \"GES_DISC\",\n  \"cmr-only\": true,\n
\"small\": true\n}\n"

Additionally, if the data stored in the file is JSON, you may have it parsed as JSON and converted Clojure's native data format, EDN:

[cmr.sample-data.dev] λ=> (pprint (data/get-ges-disc-provider [:json :edn]))
{:provider-id "GES_DISC",
 :short-name "GES_DISC",
 :cmr-only true,
 :small true}
nil

This particular sample data returns a JSON string (i.e., the :data option) by default, so you may call it with no options if that's what you need:

[cmr.sample-data.dev] λ=> (data/get-ges-disc-provider)
"{\n  \"provider-id\": \"GES_DISC\",\n  \"short-name\": \"GES_DISC\",\n  \"cmr-only\": true,\n
\"small\": true\n}\n"

The default data format returned is determined by how the CMR typically uses the data in question (i.e., what format it expects the data to be in).

For a full list of functions availble for accessing the sample data, refer to the cmr.sample-data.core source file (aliases to data in the cmr.sample-data.dev REPL namespace).
