archivematica-workflow Travis CI Coverage Status Go Report Card

archivematica-workflow is a small service used to distribute Archivematica workflows within other Archivematica services. The current implementation is limited to a single workflow extracted from the the work-in-progress Archivematica 1.7.

This is the first step toward finding better ways to describe digital preservation workflows and decoupling workflow management from our application stack.

Ongoing discussion:


archivematica-workflow is distributed as a self-contained, statically-linked binary. You can download it from the Releases page or deploy it with the Ansible role.

The only currently available workflow can be found in dist/workflows/default.json. The HTTP API and gRPC API let you access to it. Visit the proto file for more details.


Visit our Transifex project if you want to contribute in the translation of the Archivematica workflow data or in other components related to the Archivematica project.


Building from sources

Install Go 1.7 or newer and run:

$ go get -u

Binaries archivematica-workflow and archivematica-workflow-cli should now be available under $GOPATH/bin directory.

Development tools

These are some Go tools that you will need at some point if you are planning to contribute to this project as a developer. You can install them by running:

$ go get -u
$ go get -u
$ go get -u{proto,protoc-gen-go}

You will also need:

Vendoring dependencies

This repo includes a copy of its dependencies under the vendor/ directory. We use govendor to work with these dependencies. We will likely adopt dep once it matures - at the time of writing, dep is still considered pre-alpha.

govendor is very intuitive though (see cheatsheet) - these are some of the things that you can do with it:

  • Compile the sources: govendor install +local.
  • Run tests: govendor test +local.
  • List vendored dependencies: govendor list +vendor
Embedding workflows

Workflows are currently embedded into the final binary to simplify the distribution process. Further development may incorporate more sophisticated workflow management options.

The only currently available workflow is default.json. It has been generated with json-links which is part of the archivematica-devtools repository.

The schema used to encode the workflow data has not been specified yet. We're investigating better ways to do this, like linked data.

Running the following command will generate new Go code with the contents of the dist directory embedded in binary format:

$ go generate ./service/dist

The new code is checked in the repository so the application is "go gettable". In the future this step could be done as part of the build process.

Extracting workflow data from Archivematica

There is an ongoing effort in Archivematica (pull request #506) to read the workflow data using archivematica-workflow's API.

The dist/default/default.json file contains the JSON-encoded workflow data available in Archivematica (qa/1.x branch). It is generated with json-links which is part of archivematica-devtools. For example, the following command will encode the workflow database existing in your database:

$ am json-links --locale-dir=dist/workflows/locale/default dist/workflows/default.json

When --locale-dir is used, predicatably, json-links does the following things:

  • Populates the latest version of en.json so it can be pushed to Transifex (with `tx push -s).
  • Populates the translation objects in dist/workflows/default.json using the translations available under the given directory. Make sure that the translations are up todate in advance with tx pull -a.

Transifex is our localization platform. Workflow messages can be found at
