OCR-D CLI: workspace management

ocrd workspace

Managing workspaces

A workspace comprises a METS file and a directory as point of reference.

Operates on the file system directly or via a METS server (already running via some prior server start subcommand).

ocrd workspace [OPTIONS] COMMAND [ARGS]...

Options

-d, --directory <WORKSPACE_DIR>

Changes the workspace folder location [default: METS_URL directory or .]”

-M, --mets-basename <mets_basename>

METS file basename. Deprecated, use –mets/–directory

-m, --mets <METS_URL>

The path/URL of the METS file [default: WORKSPACE_DIR/mets.xml]

-U, --mets-server-url <mets_server_url>

TCP host of METS server

--backup

Backup mets.xml whenever it is saved.

Environment variables

WORKSPACE_DIR

Provide a default for -d

add

Add a file or http(s) URL FNAME to METS in a workspace. If FNAME is not an http(s) URL and is not a workspace-local existing file, try to copy to workspace.

ocrd workspace add [OPTIONS] FNAME

Options

-G, --file-grp <FILE_GRP>

Required fileGrp USE

-i, --file-id <FILE_ID>

Required ID for the file

-m, --mimetype <TYPE>

Media type of the file. Guessed from extension if not provided

-g, --page-id <PAGE_ID>

ID of the physical page

-C, --check-file-exists

Whether to ensure FNAME exists

--ignore

Do not check whether file exists.

--force

If file with ID already exists, replace it. No effect if –ignore is set.

Arguments

FNAME

Required argument

backup

Backing and restoring workspaces - dev edition

ocrd workspace backup [OPTIONS] COMMAND [ARGS]...

add

ocrd workspace backup add [OPTIONS]

list

List backups

ocrd workspace backup list [OPTIONS]

restore

Restore backup BAK

ocrd workspace backup restore [OPTIONS] BAK

Options

-f, --choose-first

Arguments

BAK

Required argument

undo

ocrd workspace backup undo [OPTIONS]

bulk-add

Add files in bulk to an OCR-D workspace.

FILE_GLOB can either be a shell glob expression to match file names, or a list of expressions or ‘-’, in which case expressions are read from STDIN.

After globbing, –regex is matched against each expression resulting from FILE_GLOB, and can define named groups reusable in the –page-id, –file-id, –mimetype, –url, –source-path and –file-grp options, e.g. by referencing the group name ‘grp’ from the regex as ‘{{ grp }}’.

If the FILE_GLOB expressions do not denote the file names themselves (but arbitrary strings for –regex matching), then use –source-path to set the actual file paths to use. (This could involve fixed strings or group references.)

Examples:

ocrd workspace bulk-add

–regex ‘(?P<fileGrp>[^/]+)/page_(?P<pageid>.*).[^.]+’

–page-id ‘PHYS_{{ pageid }}’

–file-grp “{{ fileGrp }}”

path/to/files//.*



echo “path/to/src/file.xml SEG/page_p0001.xml”

| ocrd workspace bulk-add

–regex ‘(?P<src>.*?) (?P<fileGrp>.+?)/page_(?P<pageid>.*).(?P<ext>[^.]*)’

–file-id ‘FILE_{{ fileGrp }}_{{ pageid }}’

–page-id ‘PHYS_{{ pageid }}’

–file-grp “{{ fileGrp }}”

–local-filename ‘{{ fileGrp }}/FILE_{{ pageid }}.{{ ext }}’

-

 { echo PHYS_0001 BIN FILE_0001_BIN.IMG-wolf BIN/FILE_0001_BIN.IMG-wolf.png;

echo PHYS_0001 BIN FILE_0001_BIN BIN/FILE_0001_BIN.xml; echo PHYS_0002 BIN FILE_0002_BIN.IMG-wolf BIN/FILE_0002_BIN.IMG-wolf.png; echo PHYS_0002 BIN FILE_0002_BIN BIN/FILE_0002_BIN.xml;

} | ocrd workspace bulk-add -r ‘(?P<pageid>.*) (?P<filegrp>.*) (?P<fileid>.*) (?P<local_filename>.*)’
