Migration Tool

The migration tool provides a multi-platform CLI tool to use data migration functions for Cadmus databases.

Dump Command

🎯 Dump any subset of Cadmus data objects into JSON file(s).

Syntax:

./cadmus-mig dump <DatabaseName> [-i] [--no-part-date] [--no-deleted] [--no-parts] [-o OutputDirectory] [--max-file-items N] [--indented] [-w PartTypeKey] [-b PartTypeKey] [-u UserId] [-n MinModified] [-m MaxModified] [-t Title] [--description Description] [-f FacetId] [-g GroupId] [-l Flags] [--flag-matching AllSet|AnySet|AllClear|AnyClear] [-p PageNumber] [-s PageSize]

• DatabaseName: the Cadmus database name. The MongoDB connection string template to use is specified in the CLI appsettings.json configuration file. In it, {0} is the placeholder for the database name.
• -i: incremental dump, including only items/parts changed in the timeframe.
• --no-part-date: do not consider parts’ date when filtering items by time-based parameters.
• --no-deleted: do not include deleted items.
• --no-parts: do not include parts in exported items.
• -o OutputDirectory: the output directory. If not specified, a desktop folder with the current date will be used. If the folder does not exist, it will be created.
• --max-file-items N: The maximum number of items to export per file. If not specified (0), all items will be exported in a single file.
• --indented: indent JSON output.
• -w PartTypeKey: the keys of the part types to include in the export with form typeId[:roleId]. Can be used multiple times, one per part type. If not specified, all part types are included.
• -b PartTypeKey: the keys of the part types to exclude in the export with form typeId[:roleId]. Can be used multiple times, one per part type. If not specified, no part types are excluded.
• -u UserId: the user ID to filter items by. If not specified, items by all users are included.
• -n MinModified: the minimum modified date and time filter.
• -m MaxModified: the maximum modified date and time filter.
• -t Title: the item’s title filter (any portion of it).
• --description Description: the item’s description filter (any portion of it).
• -f FacetId: the item’s facet ID.
• -g GroupId: the item’s group ID.
• -l Flags: the item’s flags. This is a numeric value representing a bitset where each bit is a flag.
• --flag-matching AllSet|AnySet|AllClear|AnyClear: the item’s flags matching mode.
• -p PageNumber: the page number (1-N), when you want just a page of results.
• -s PageSize: the page size. By default this is 0, i.e. there is no paging.

Example:

./cadmus-mig dump cadmus-ndp --indented

Dump Thesauri Command

🎯 Dump all the thesauri into a JSON file.

Syntax:

./cadmus-mig dump-thesauri <DatabaseName> [-o OutputPath] [--indented]

• DatabaseName: the Cadmus database name. The MongoDB connection string template to use is specified in the CLI appsettings.json configuration file. In it, {0} is the placeholder for the database name.
• -o OutputPath: the output JSON file path.
• --indented: indent JSON output.

Render Items Command

🎯 Render Cadmus items.

Syntax:

./cadmus-mig render <DatabaseName> <ConfigPath> [-p PluginTag] [-r PluginTag] [-c ComposerKey] [-m MaxItemsCount]

• DatabaseName: the Cadmus database name. The MongoDB connection string template to use is specified in the CLI appsettings.json configuration file. In it, {0} is the placeholder for the database name.
• ConfigPath: the path to the rendering pipeline configuration file.
• -p PluginTag: the tag of the factory provider plugin for preview (ICadmusRenderingFactoryProvider).
• -r PluginTag: the tag of the Cadmus repository provider plugin (IRepositoryProvider).
• -c ComposerKey: the item composer key to use (default is default).
• -m MaxItemsCount: the maximum number of items to render (0=all).

Export RDF Command

🎯 Export Cadmus semantic graph into various standard RDF formats.

Syntax:

./cadmus-mig export-rdf <DatabaseName> <OutputPath> [-f Format] [--p true|false] [-c true|false] [--base-uri URI] [--batch-size Size] [--r true|false] [--export-referenced-nodes-only true|false] [--node-tag-filter Tags] [--triple-tag-filter Tags] [--encoding Encoding]

• DatabaseName: the Cadmus database name. The MongoDB connection string template to use is specified in the CLI appsettings.json configuration file. In it, {0} is the placeholder for the database name.
• OutputPath: the output file path.
• -f Format: the format to export (turtle, rdfxml, rdfowlxml, ntriples, jsonld). Default is turtle.
• -p or --include-prefixes: include prefix declarations in the output. Default is true.
• -c or --include-comments: include comments in the output. Default is true.
• --base-uri URI: the base URI to use for relative URIs. If null or empty, no base URI is used.
• --batch-size Size: maximum number of triples to process in a single batch. Default is 10000.
• -r or --pretty-print: pretty-print the output (add indentation and line breaks). Default is true.
• --export-referenced-nodes-only: export only nodes that are referenced in triples. Default is false (exports all nodes).
• --node-tag-filter: optional filter for node tags. If specified, only nodes with matching tags are exported. Comma-separated.
• --triple-tag-filter Tags: optional filter for triple tags. If specified, only triples with matching tags are exported. Comma-separated.
• –encoding Encoding: the character encoding to use for output files. Default is UTF-8.

Examples:

• Turtle: a compact, human-readable syntax for RDF. Great for editing and reading manually (https://www.w3.org/TR/rdf12-turtle/).
