To publish data to a catalog:
You must have a HERE platform account to proceed. If you do not have an account, contact your organization's HERE platform administrator and request to be invited to the HERE platform as described in Add and Manage Groups.
In order for your application to write data to the HERE platform, you must register your application by generating an ID and credentials for the application. For instructions, see Manage Apps.
Once you have registered your application, share the catalog with the app. For instructions, see Share a catalog.
You cannot publish data to a catalog unless the catalog is shared with the app ID.
To publish data to a versioned or volatile layer, use HERE platform Data Client Library. The Data Client Library provides Java/Scala libraries for publishing data to HERE platform catalogs.
Make sure your system has the required software installed. For the list of the required software, see Configure your environment. Your environment is set up correctly if there are no errors.
To use the Data Client Library in your Maven project, add the following snippet to your
<repositories> <repository> <id>HERE_PLATFORM_ARTIFACT</id> <layout>default</layout> <url>here+artifact-service://artifact-service</url> </repository> </repositories> <dependencies> <dependency> <groupId>com.here.platform.data.client</groupId> <artifactId>data-engine_2.12</artifactId> <version>1.18.79</version> </dependency> </dependencies> <build> <extensions> <extension> <groupId>com.here.platform.artifact</groupId> <artifactId>artifact-wagon</artifactId> <version>2.0.13</version> </extension> </extensions> </build>
To use the Data Client Library in your SBT project, add the following snippet to your
addSbtPlugin("com.here.platform.artifact" % "sbt-resolver" % "2.0.14")
And add the following snippet in your
resolvers += "HERE_PLATFORM_ARTIFACT" at "here+artifact-service://artifact-service" libraryDependencies += "com.here.platform.data.client" %% "data-engine" % "1.18.79"
The SBT resolver plugin is provided 'as is' and not officially part of Marketplace. While there is no official support by HERE, you may still raise issues via GitHub.
HERE may be able to help.
Now that you have set up your environment, see Publish Data in the Data Client Library Developer Guide for information on using the Data Client Library to publish data to a catalog.
To publish data to a stream layer, use the
ingest REST API.
To get started, you must get credentials and an authorization token for your REST requests. See "Get Credentials" and "Get an authorization token" in the Get started section of the Data API Developer Guide.
Next, get the base URL for the
ingest API for the catalog you want to publish using the
api-lookup service. See "Get the API base URLs for a catalog" in the Get started section of the Data API Developer Guide.
Once you have credentials and an authorization token, you can publish data following the instructions in "Publish up to 20 MB of data in a request" in the Publish data to a stream layer section of the Data API Developer Guide.
Marketplace users must use the
ingest API to write data to a stream layer, so you must follow the procedure described in "Publish 1 MB or Less of Data" to publish data to a stream layer. This is necessary so that metrics can be calculated.
Here are the key concepts you should understand related to HERE platform data:
