List lists the version names of the specified objects, if only a component is specified all versions according to the given versuin constraints are listed.

If the option –constraints is given, and no version is specified for a component, only versions matching the given version constraints (semver are selected. With –latest only the latest matching versions will be selected.

If the –repo option is specified, the given names are interpreted relative to the specified repository using the syntax


If no –repo option is specified the given names are interpreted as located OCM component version references:

[<repo type>::]<host>[:<port>][/<base path>]//<component>[:<version>]

Additionally there is a variant to denote common transport archives and general repository specifications

[<repo type>::]<filepath>|<spec json>[//<component>[:<version>]]

The –repo option takes an OCM repository specification:

[<repo type>::]<configured name>|<file path>|<spec json>

For the Common Transport Format the types directory, tar or tgz is possible.

Using the JSON variant any repository types supported by the linked library can be used:

Dedicated OCM repository types:

  • ComponentArchive: v1

OCI Repository types (using standard component repository to OCI mapping):

  • CommonTransportFormat: v1
  • OCIRegistry: v1
  • oci: v1
  • ociRegistry

If a component lookup for building a reference closure is required the –lookup option can be used to specify a fallback lookup repository. By default, the component versions are searched in the repository holding the component version for which the closure is determined. For Component Archives this is never possible, because it only contains a single component version. Therefore, in this scenario this option must always be specified to be able to follow component references.

If the option –scheme is given, the component descriptor is converted to the specified format for output. If no format is given the storage format of the actual descriptor is used or, for new ones v2 is used. With internal the internal representation is shown. The following schema versions are supported for explicit conversions:

  • v2

With the option –output the output mode can be selected. The following modes are supported:

  • (default)
  • JSON
  • json
  • yaml
