SDL Trados 2007: Translation Memory Strategies

What is the best way to organise and maintain Translation Memories?

I currently maintain TMs using 2 features of Trados (the Attributes and Master/Project TM dichotomy) and Alchemy’s Trados component.

Master TMs

• single and exhaustive repository for each field and language pair (e.g. EN-FR Medical).
• used to analyse all new projects and generate Project TMs.
• content of Project TMs are only added to it when full project cycle has ended (including review, QA etc.).
• because of their exhaustive nature, Master TMs tend to grow rapidely and would not be practical for inclusion into a translation kits.
• even when outsourcing all or most of the localisation process, these should always be held by the client as they are a valuable asset which they own, regardless of whether they are outsourcing TM Management.

Project TMs

• specific to a project or project stage (i.e. successive handoffs of a same project often have their own Project TMs).
• used to pre-translate the handoff (i.e. generate the TTX files to send to the vendor).
• passed on to translation vendors for analysis and use during interactive translation.
• used during post-translation engineering (bugs are fixed in Workbench + TagEditor + MultiTerm interactive translation environment by the localisation engineer).

Software TMs

• single and exhaustive repository for each field and language pair, generated bi-yearly from Catalyst TTKs.
• added to Master TM of their field and/or used as Concordance reference during translation of help, documentation, knowledge base articles etc.
• also used as leverage source for software through Catalyst.

Use of attributes

• every time a new project is analysed, custom attributes are added and set (e.g. Vendor=AAA, Project=XXX, Field=FFF).
• can be used to filter searches and analyses.
• also useful to track back on errors or arbitrate between duplications.
