Can I distribute Mayan EDMS under another name and/or logo?
Yes, the terms of the license allow this. However, the copyright notice must remain intact. If you use an alternate name, a notice indicating that yours is a derived product from Mayan EDMS must be included. You must indicate to your clients that their act of purchasing Mayan EDMS from you is an independent action and in no way legally binds Mayan EDMS LLC, the Mayan EDMS copyright holder, or the core team in any way.
Can I sell Mayan EDMS as is or under another name?
Yes, selling Mayan EDMS is permitted. However, the copyright notice must remain intact. If you use an alternate name, a notice indicating that yours is a derived product from Mayan EDMS must be included. You must indicate to your clients that their act of purchasing Mayan EDMS from you is an independent action and in no way legally binds Mayan EDMS LLC, the Mayan EDMS copyright holder, or the core team in any way. Note that when you sell Mayan EDMS, you are selling your service and not a license, rights, or privileges of any type.
Can I get exclusive distribution rights for my region?
No, the terms of the license make the project freely available to everyone. Restricting distribution or sale would conflict with the license terms. This would possible if there was a commercial version of Mayan EDMS with separate licensing terms.
Is there a commercial partnership program?
There was at one time but was retired. If there is interest it could be reinstated in the future.
What is an EDMS?
EDMS stands for Electronic Document Management System and it is an more modern version of a DMS. A DMS is a Document Management System. A system to store, sort, and categorize printed documents. It is an electronic filing system. Besides images of scanned documents, an EDMS also support electronic documents, documents created in a computer that may or may not have been printed. While they may look similar, EDMS/DMS is not to be confused with CMS (Content Management System), IM (Information Management), KM (Knowledge Management), RM (Record management), ECM (Enterprise Content Management). Mayan EDMS started initially as a strict EDMS project but has been expanding its feature set and provide some functionality from other system types.
PostgreSQL vs. MySQL
Since Django abstracts database operations from a functional point of view Mayan EDMS will behave exactly the same either way. The only concern would be that MySQL doesn’t support transactions for schema modifying commands. The only moment this could cause problems is when running South migrations during upgrades, if a migration fails the database structure is left in a transitory state and has to be reverted manually before trying again.
_mysql_exceptions. OperationalError: (1267, “Illegal mix of collations (latin1_swedish_ci, IMPLICIT) and (utf8_general_ci, COERCIBLE) for operation ‘=’”)
$ mayan-edms.py shell >>> from django.db import connection >>> cursor = connection.cursor() >>> cursor.execute('SHOW TABLES') >>> results= >>> for row in cursor.fetchall(): results.append(row) >>> for row in results: cursor.execute('ALTER TABLE %s CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;' % (row))
Incorrect string value: ``’xE2x80x95rs6…’`` for column ``’content’`` at row 1
When using MySQL and doing OCR on languages other than English
Solution: Use utf-8 collation on MySQL server, or at least in table ‘documents_documentpage’, ‘content’ field
Error “django.db.utils.IntegrityError IntegrityError: (1452, ‘Cannot add or update a child row: a foreign key constraint fails (`…`.`…`, CONSTRAINT `…_refs_id_b0252274` FOREIGN KEY (`…`) REFERENCES `…` (`…`))’)
Solution: Convert all MySQL tables to the same type, either all MyISAM or InnoDB
How do you upload a new version of an existing file?
Solution: Choose a document, and go to the versions tab, on the right menu at the bottom under Other available action there is Upload new version. Clicking it will take you to a very similar view as the Upload new document but you will be able to specify version number and comments for the new version being uploaded.
How to do LDAP authentication
A sample settings file called ldap_connection_settings.py is included in the contrib/settings/ folder of the repository showing how to setup LDAP authentication.
How to install Mayan EDMS in Windows operating systems?
Mayan EDMS doesn't run natively on Windows. The best way is to use a virtual machine product, install Ubuntu or Debian, and proceed with the standard deployment instructions or use Docker inside a GNU/Linux virtual machine.
How to install Mayan EDMS on FreeBSD?
None of the core team members is knowledgeable in BSD systems and can't provide an installation plan at the moment. If community members have installed Mayan EDMS on BSD systems and provide the steps used these could be added to this Wiki.
Is virtualenv required as specified in the documentation?
It is not necessary, but it’s a strong recommendation mainly to reduce dependency conflicts by isolation from the main Python system install. If not using a virtualenv, pip would install Mayan’s dependencies globally coming in conflict with the distribution’s prepackaged Python libraries messing other Django projects or Python programs, or another later Python/Django project dependencies coming into conflict causing Mayan to stop working for no apparent reason.
Does Mayan EDMS work with Python 3?
Not at the moment. When all the projects and libraries upon which Mayan is dependent support Python 3 then will the project move to fully support Python 3.
Update 2018-06-04: Python 3 will be required from Django 2.0 onwards. As such this is now a bigger priority and the transition to Python 3 has begun.
Mayan EDMS installed correctly and works, but static files are not served
Django’s development server doesn’t serve static files unless the DEBUG option is set to True, this mode of operation should only be used for development or testing. For production deployments the management command:
$ mayan-edms.py collectstatic
should be used and the resulting static folder served from a webserver. For more information, read https://docs.djangoproject.com/en/dev/howto/static-files/ and https://docs.djangoproject.com/en/1.2/howto/static-files/ or http://mayan-edms-ru.blogspot.com/2011/11/blog-post_09.html
The watched folder feature is not working
Make sure that the Celery BEAT scheduler is running correctly as it is the element that triggers the periodics tasks.
Disable unix extensions in the [global] section and enable wide links for the file serving share
[global] unix extensions = no ... [digitalizacion] path = /var/local/mayan guest ok = yes read only = yes wide links = yes follow symlinks = yes
Can you change the display order of documents…i.e can they be in alphabetical order?
A the moment no, but it is something being considered.
