class ocdskit.packager.Packager

The Packager context manager helps to build a single record package, or a stream of compiled releases or merged releases. Release packages and/or individual releases can be added to the packager. All releases should use the same version of OCDS.

add(data)

Adds release packages and/or individual releases to be merged.

Parameters:data – an iterable of release packages and individual releases Raises:InconsistentVersionError – if the versions are inconsistent across packages to merge

output_package(merger, return_versioned_release=False, use_linked_releases=False, streaming=False)

Yields a record package.

Parameters:

• merger (ocdsmerge.merge.Merger) – a merger
• return_versioned_release (bool) – whether to include versioned releases in the record package
• use_linked_releases (bool) – whether to use linked releases instead of full releases, if possible
• streaming (bool) – whether to set the package’s records to a generator instead of a list

output_records(merger, return_versioned_release=False, use_linked_releases=False)

Yields records, ordered by OCID.

Parameters:

• merger (ocdsmerge.merge.Merger) – a merger
• return_versioned_release (bool) – whether to include versioned releases in the record package
• use_linked_releases (bool) – whether to use linked releases instead of full releases, if possible

output_releases(merger, return_versioned_release=False)

Yields compiled releases or versioned releases, ordered by OCID.

Parameters:

• merger (ocdsmerge.merge.Merger) – a merger
• return_versioned_release (bool) – whether to yield versioned releases instead of compiled releases

class ocdskit.packager.AbstractBackend

add_release(release, package_uri)

Adds a release to the backend. (The release might be added to an internal buffer.)

Raises:MissingOcidKeyError – if the release is missing an ocid field

get_releases_by_ocid()

Yields an OCIDs and an iterable of tuples of (ocid, package_uri, release).

OCIDs are yielded in alphabetical order. The iterable is in any order.

flush()

Flushes the internal buffer of releases. This may be a no-op on some backends.

close()

Tidies up any resources used by the backend. This may be a no-op on some backends.

get_releases_by_ocid()

OCIDs are yielded in alphabetical order. The iterable is in any order.

class ocdskit.packager.SQLiteBackend

flush()
