Project Metadata
A project’s metadata typically contains a number of database connections (relational or NoSQL), logging configurations and so on. This metadata is stored on a project level and is available through the metadata perspective.
The way metadata typically is handled is:
-
metadata objects (connections, logging, …) are defined on a project level. E.g. a
CRM
database connection is created in the project, using a number of variables for hostname (${CRM_HOST}
) and database name (${CRM_DBNAME}
), with corresponding variables for the port, username, password and so on. -
the metadata object configuration is defined on an environment level, where a number of variable values are created the contain the ip address for
${CRM_HOST}
etc.
A project’s metadata is stored in ${PROJECT_HOME}/metadata
, but can be overruled by setting the project’s metadata base folder ${HOP_METADATA_FOLDER}
property in the project configuration dialog or directly in the project-config.json
file.
A basic project metadata folder will look similar to the one below:
