Glossaries in DeepL: Understanding the Distinction

Note: This section is purely intended to clarify the situation with regard to using DeepL glossaries.  Glossary support is currently being worked on by the Trados AppStore Team.

When working with DeepL, it's essential to understand the difference between glossaries created via the DeepL API through a CAT tool integration, and those created directly via the DeepL website or DeepL apps.

Glossaries Created via the DeepL API

Accessibility: These glossaries are only accessible through the specific application, tool, or plugin that created them, such as the DeepL plugin for Trados Studio.

Integration: They are not integrated with or synchronized to the glossaries created through the DeepL website or DeepL apps.

Management: Creation, deletion, and other management must be handled through the API or the specific tool that uses the API.  Note that direct editing is not possible; changes require complete deletion of the glossary and recreation.

Glossaries Created via the DeepL Website and Apps

Accessibility: These glossaries are accessible through the DeepL website and DeepL's native apps.

Integration: They are not integrated with or synchronized to the glossaries created via the DeepL API.

Management: Creation, deletion, and other management must be handled through the DeepL website or apps.

Practical Implications

Separation of Resources: Be aware that glossaries created in one context (API or website/apps) are not accessible in the other.

Potential for Confusion: Users expecting a unified experience will need to understand that these glossaries are distinct and independent.

Current Recommendations from DeepL

Glossary Support is now offered via a dropdown based on supported language pair

The following features are supported

1. Create Glossary 
   When creating a glossary, you have an empty database whereby you can manually add new entries
2. Import
   Use this feature when managing glossaies between platforms. By default the name of your glossary will match the name of your imported file, but this can be changed using the edit feature
3. Export
   Supported formats being *.TSV & *.CSV
4. Batch Import
   This supports the import of a file into existing glossaries
5. Delete
6. Edit Glossary

Once your glossary has been created, you cant change the name of your glossary.
However you can edit term entries

When editing your glossary the following features are supported:

• Delete entry
• Add entry
• Import into Glossary
• Edit entry

Glossaries Restrictions

1. Import file format
   
   The format of the import can either be *.TSV & *.CSV (delimited by either a semi colon or comma). The placement of source / target terms within your file, should directly correlate with the supported language direction defined during import
   
   

   Common Restrictions for All Glossary Formats

   • Duplicate source entries are not allowed
   • Neither source nor target entry may be empty
   • Source and target entries must not contain any C0 or C1 control characters (including, e.g., "\t" or "\n") or any Unicode newline
     
     
2.  Limits imposed
   
   You can create up to 1,000 glossaries. Please keep in mind that the maximum size limit for a glossary is 10 MB and each source/target text as well as the name of the glossary is limited to 1024 UTF-8 bytes.
   Editing existing DeepL API Glossaies is not supported by DeepL. You can implement the edit functionality yourself by creating a new glossary with the modified entries and deleting the old glossary.
   
   
3. At the time of when these notes were made the supported languages from DeepL was limited to:

• Chinese (simplified)
• Dutch
• English
• French
• German
• Italian
• Japanese
• Polish
• Portuguese
• Russian
• Spanish

How the plugin works

Trados Studio

After the plugin has been installed you can access it in Studio by going to your Project Settings -> All Language Pairs->Translation Memory and Automated Translation and then click on the Use... button to expand the options:

A new window will appear where you can introduce your API Key .  The API Key text box is a required field, so if you don't fill it and click OK the window will not close and instead an warning message will appear.  It's also worth noting that if you cannot close the window after adding your key it may help to add a space to the end of the key and then delete it.  That should activate the OK button:

To close the window use "Cancel" button or "X" from the top right of the window

Language Cloud

The Language Cloud add-on is available through the RWS AppStore here - https://appstore.rws.com/plugin/140/.  When you "download" the application you will be redirected and asked to sign in to your language cloud account.  If you don't have one you won't be able to access the application at all.

There is no installation on your computer required as the installation takes place in your Language Cloud account where you will see something like this:

Clicking on the link will take you to the installation page where you simply click Install:

You'll then be asked for your API key to activate it so it's available to you for translating in the cloud:

Troubleshooting:

Sometimes errors can be reported when trying to get a translation result from DeepL.  This may be related to firewall restrictions which can be resolved by whitelisting the following domains:
