DocuWare REST-API client

docuware-client

This is a client library for the REST API of DocuWare DMS. Since DocuWare's documentation regarding the REST API is very sparse (at the time these lines were written), this client serves only a part of the API's functionality.

Please keep in mind: This software is not related to DocuWare. It is a work in progress, may yield unexpected results, and almost certainly contains bugs.

Usage

First you have to log in and create a persistent session:

import json
import pathlib
import docuware

dw = docuware.Client("http://localhost")
session = dw.login("username", "password", "organization")
with open(".session", "w") as f:
    json.dump(session, f)

From then on you have to reuse the session, otherwise you will be locked out of the DocuWare server for a period of time (10 minutes or longer). As the session cookie may change on subsequent logins, update the session file on every login.

session_file = pathlib.Path(".session")
if session_file.exists():
    with open(session_file) as f:
        session = json.load(f)
else:
    session = None
dw = docuware.Client("http://localhost")
session = dw.login("username", "password", "organization", cookiejar=session)
with open(session_file, "w") as f:
    json.dump(session, f)

Iterate over the organizations and file cabinets:

for org in dw.organizations:
    print(org)
    for fc in org.file_cabinets:
        print("   ", fc)

If you already know the ID or name of the objects, you can also access them directly.

org = dw.organization("1")
fc = org.file_cabinet("Archive")

Now some examples of how to search for documents. First you need a search dialog:

# Let's use the first one:
dlg = fc.search_dialog()
# Or a specific search dialog:
dlg = fc.search_dialog("Default search dialog")

Each search term consists of a field name and a search pattern. Each search dialog knows its fields:

for field in dlg.fields.values():
    print(field)

Let's search for some documents:

# Search for DOCNO equal to '123456':
for result in dlg.search("DOCNO=123456"):
    print(result)
# Search for two patterns alternatively:
for result in dlg.search(["DOCNO=123456", "DOCNO=654321"], operation=docuware.OR):
    print(result)

Please note that search terms may also contain metacharacters such as *, (, ), which may need to be escaped when searching for these characters themselves.

for result in dlg.search("DOCTYPE=Invoice \\(incoming\\)"):
    print(result)

Search terms can be as simple as a single string, but can also be more complex. The following two queries are equivalent:

dlg.search(["FIELD1=TERM1,TERM2", "FIELD2=TERM3"])
dlg.search({"FIELD1": ["TERM1", "TERM2"], "FIELD2": ["TERM3"]})

The result of a search is always an iterator over the search results, even if no result was obtained. Each individual search result holds a document attribute, which gives access to the document in the archive. The document itself can be downloaded as a whole or only individual attachments.

for result in dlg.search("DOCNO=123456"):
    doc = result.document
    # Download the complete document ...
    data, content_type, filename = doc.download(keep_annotations=True)
    docuware.write_binary_file(data, filename)
    # ... or individual attachments (or sections, as DocuWare calls them)
    for att in doc.attachments:
        data, content_type, filename = att.download()
        docuware.write_binary_file(data, filename)

CLI usage

This package also includes a simple CLI program for collecting information about the archive and searching and downloading documents or attachments.

First you need to log in:

$ dw-client login --url http://localhost/ --username "Doe, John" --password FooBar --organization "Doe Inc."

The credentials and the session cookie are stored in the .credentials and .session files in the current directory.

Of course, --help will give you a list of all options:

$ dw-client --help

Some search examples (Bash shell syntax):

$ dw-client search --file-cabinet Archive Customer=Foo\*
$ dw-client search --file-cabinet Archive DocNo=123456 "DocType=Invoice \\(incoming\\)"
$ dw-client search --file-cabinet Archive DocDate=2022-02-14

Downloading documents:

$ dw-client search --file-cabinet Archive Customer=Foo\* --download document --annotations

Downloading attachments (or sections):

$ dw-client search --file-cabinet Archive DocNo=123456 --download attachments

Some information about your DocuWare installation:

$ dw-client info

Listing all organizations, file cabinets and dialogs at once:

$ dw-client list

A more specific list, only one file cabinet:

$ dw-client list --file-cabinet Archive

You can also display a (partial) selection of the contents of individual fields:

$ dw-client list --file-cabinet Archive --dialog custom --field DocNo(partial)
