1. While the database clean-up operation removes unneeded data from the database, the database’s actual size on the disk will not decrease until a shrink operation is performed on the database in question. This must be executed on the database directly by the database administrator


  1. Modeler is not compatible with Windows 10
  2. Modelpedia is not compatible with the Microsoft Edge web browser
  3. By default, Chrome browser 37.0.2062.103 m and later renders some fonts differently to previous versions. This affects some fonts in Modelpedia, as well as many other websites. In order to revert the fonts to their correct defaults, perform the following:
    1. Open the Flags configuration in Chrome by navigating to chrome://flags/
    2. Disable DirectWrite (click the Enable link so that it reads Disable)
    3. Restart Chrome by closing it or clicking on the Relaunch Now button
  4. External Document References to files (file://) do not open in Chrome browser. This Chrome browser limitation can be worked around by installing browser plugins
  5. When using any versions of Internet Explorer greater than 9, the Modelpedia server must be added to trusted sites in order to be able to open External Document Reference links to network drive locations (\\servername\)

Known Issues, Warnings and Limitations

  1. The Modelpedia service account must be added to the Licensed User Group if using a Named License key
  2. It is not possible to undo database clean-ups. It is recommended that backups be made before commencing, so that the database can be replaced by the backup should a reversion be desired
  3. A database clean-up job cannot run concurrently with any other type of queued job. Clean-up jobs will wait until there are no other jobs running before beginning, and no other jobs will begin while the clean-up job is in progress
  4. Clean-up jobs are resource intensive and may cause performance issues on the Modelpedia server while they are running. It is recommended that clean-up operations be conducted outside of peak usage hours
  5.  There is a small chance that model check-ins may fail while a clean-up job is running. It is recommended that clean-up operations be conducted outside of peak usage hours
  6. Users cannot delete permission granting Context Authority Roles (CAR) which they are a member of, if deleting the CAR would result in the user’s loss of the delete permission
  7. Search inputs in Modeler no longer recognise regular expression (regex) strings, but accept wildcards (*) instead
  8. User visibility has been adjusted so that two members of a group cannot see each other, unless they are also members of the same organisation
  9. The Users page in the Administration Portal may not be available when there are more than 20,000 Modelpedia users registered on the server
  10. In the Modeler Repository Workspace, any user property windows which are open when the Repository Explorer’s Show All Areas option is toggled will be closed
  11. Times recorded in Modeler may be out by an hour. Due to the manner in which systems times are recorded in Windows, it is possible that the daylight savings modifier on timestamps has been dropped or incorrectly added. Owing to the nature of the issue, it is impossible to automatically determine and correct the time offset
  12. Only one library can be published on a Modelpedia server at a time. Other publication requests will be queued and processed in the order in which they were received
  13. Only one published library can be initialised at a time. Other libraries which need to be initialised are queued and processed when the current initialisation process is completed
  14. Toggling status colours for published Modelpedia websites only affects the appearance to the names of items in the Types and Catalog views. Diagrams appear in published form exactly as presented in Modeler
  15. When switching between full screen and windowed mode in browsers, it is possible that diagram tabs may become desynchronised from their intended positions and wander off the screen. Performing a refresh of the web browser will revert the tabs to their correct positions
  16. Changing published libraries’ Release states and Show Revisions settings will cause the cache for the published library to reset, making the next visit to the site slightly slower
  17. Hyperlink labels which exceed 72 characters are truncated
  18. Adding compressed (.zip files) to libraries as Content can cause the libraries to fail publication
  19. Using large JPEG images in models can cause degraded publishing performance and increase published content size, and is therefore not recommended. Use smaller images of the BMP or PNG type instead of JPEG where possible
  20. The published website setting to show item status colour only affects items displayed in the Catalog or Type menus in Modelpedia. If diagrams are published with status colours enabled, the website must be republished in order for the changes to diagrams to be visible
