Priority 1: Need to be done before the Oct 7 demo at Translation Bureau

1.0- LANGS_HALF_AND_HALF Side by side languages should always occupy 50% of the available space each

P1.1- COMMENTS_NOT_APPEARING (LPH): When you fill the comments form, comments never appear

P1.1- SHOW_ALL_LANGUAGES_WHEN_JUMPING_STRAIGHT_TO_TERM

P1.1 - Extensive help pages

• Help pages should cover all the common tasks.
• In particualr, it should provide instructions about how to deal with the situation where a same word can refer to different things. For example, Tag can refer to metadata, to a markup element, or to a dog tag. The solution is to create pages with slightly different names, for example "tag - metadata", "tag - markup", "tag - identity plaque".
• Refactor the instructions pages into one long page called "Guide to collaborative multilingual terminology creation". The guide will have a section for Admins, and a section for Editors.
  • Section for editors comes first.
  • Section for editors talks about:
    • Searching for a term
    • Creating a new term
    • Creating an equivalent for a term
    • What to do if a same word can mean different things (create different pages which are more explicit, ex: tag — dog plaque, vs tag — metadata).
    • Tracking certain pages or the whole site
    • Using categories for domain classification
  • Section for admins talks about:
    • Finalizing the installation
    • Keeping abreast of new users
    • Approving new users
    • Tracking the whole site
• The guide should provide instructions about using categories to assign domains. The admin section should suggest that the admin seed the category tree.
• Guide should provide instructions about how to manage users.
  • Ask for email notification of new users.
  • Move new users from Registered to Editors soon after registering.
  • What are the different groups and their permissions.
• Guide should bring users attention to the Last changes module as a way to keep track of what others do. Also, explain the page tracking feature.
• How do I set up the glossary profile and make it multilingual?
• How do I create a glossary entry in say, French?
• Given an entry in say, French, how do I create the corresponding entry in say, English?
• How do I avoid reinventing the wheel? For example, say I create a French entry for word X, and then want to create the corresponding entry Y in English, but someone already created Y, how do I find out about it and tie the two together. In particular, what happens if the existing Y is a very slight variation on the Y that I am currently trying to create (eg: I am creating the verb form, whereas the existing Y used the noun form)?
• I don't want to change an entry... just comment on it.
• How can I respond to someone else's comment?
• Can I create an entry in French that has more than one English equivalent?
• How do I create a domain hierarchy?
• Admin: What is the current permissions scheme, and how do I customize it for my needs?
• How do I specify my source and target language?
• How do I enable a new language?
  • HOw to enable that language in the prefs panel
  • Create a new template for an entry in that language
• Admin: How do I monitor spam, etc...
• Admin: What to do when a new user registers?
• User: how do I ask a terminology queston
  • Create a terminology entry for it, and put a comment asking for its translation.
  • Or, post the question on appropriate discussion forum. Once you have decided which is best, please create a bilingual terminology entry so people will find it more easily later.
• User: How to keep abreast of what's going on?
  • Can ask to watch the whole site...
  • Or, can ask to watch a partiular forum
  • By default, may be notified of changes made to pages you created, or to forum posts that you create.

P1.1 Translate guide to French

• Make it so that the guide is available in French and English.

Priority 2: These should be done before we actually deploy the system on pilot operational site

P2.0- ADMIN_CAN_CHANGE_SITE_DEFAULT_LANG

P2.1- LINKS4ANONS Anons should see links to home page and forum

• Activating the My Tiki menu or module for anons (includes links to home and to forums)
• Add links to the home or forum to the terminology module.
• Or, create a customized menu in the profile, as per this url: http://profiles.tikiwiki.org/Collaborative_Community#Menu

Priority 3: These should be fixed before we advertise the profile widely

P3.0- USER_LANGS_DOES_NOT_CHANGE_SEARCH_LANGS

P3.1 COMMENTS_HIDDEN- Coments should be hidden by default

P3.2- LANG_CHOICE_FOR_ANONS (Alain will fine tune it): Terminology module does not offer possibility to search in French

Priority 4: These are additional new features that should eventually be added

Simple approval, versus to be approved status

• Create a category to capture that.
• Category is displayed on the page.
• Can modify it by editig the page and changing the category.
• In version 4, possible to set permissions on the page so that only say, Admins can set that particualr category.
• There is a page listing all pages that fit a particular category (ex: "Need approval").

PROGRAMMATION: When translating to an existing page name, system should offer you to link the two of them

PROGRAMMATION: Forum postings should allow empty text

PROGRAMMATION: Make it possible to use Categories for domains

• Should editors be allowed to create/modify/delete categories, or should it just be admins?
• May need to change code a bit so that the categories don't take so much real estate.
• Should each category be multilingual, or should we have parallel category hierarchies in different language?

Figure out the right level of tracking

• By default, users should be setup to track certain things. What should those things be:
  • Track pages that they themselves created?
  • Track creation of new pages (i.e. new terms), so that they can track implicit terminology questions from other users?

Tracking a page should also track its translations

• If I create a term in English for which I don't know the French equivalent, as a way of implictly asking a question. Then, when someone actually translates that page to create a French equivalent, I should be notified of that.
• But right now, that does not happen.
• Note: Maybe a better way to ask a question is to use a discussion forum. See todo regarding forum.

Simple approval mechanism for terms

• A category Status with sub categories Approved, Needs Approval.
• By default, all pages are assigned Needs Approval.
• Only a certain group (Ex: Terminologists) are allowed to change that category.
• There is a page listing all pages with Needs Approval.

When translating, only list languages that I speak

Automatically select language of equivalent when possible

• If I translate a term to another language, if there is only one language left in the user's language preferences, for which a translation of that term does not exist, then automatically select that language by default.
• For example, if I have set only En and Fr as my languages, and I am translating an En term, then system should automatically select Fr by default for the translated page.

Allow people to vote on the best equivalent

Terminology module should validate that Terminology PROFILE has been applied

• The Terminology module should check that the Terminology profile has been applied. If it hasn't, it should display a highly visible warning telling the admin to apply that profile (and providing a link with instructions on how to do this... for example, a link to the profile itself, and the profile would have instructions on how to apply it.)
  • Done, but the link that points to how to install the profile could be more specific. It could point to the admin page for applying the profile.

Automatic translation of labels when creating an equivalent

• Say I have a page "web browser", and I want to create its French equivalent "navigateur web".
• I click on Translate button.
• The content of the English page is pasted into the French page.
• The problem is that all the labels like Synonyms, Definition, must be translated.
• And they need to be translated in a standardized way.
• It would be nice if these could be translated automatically.
• Here's a generic way in which this could be done.
• When we create a new translation, the system will automatically translate occurrences of an English page name, to the name of the corresponding French page.
• So, now all we need to do create an English page Synonym with a French equivalent Synonymes.
• This feature would be useful in other ways.
• It would automatically translate links to English pages into links to French pages.
• It would automatically translate English terminology to French terminology (often, terms are captured as pages, even on sites where Terminology profile is not used).
• Question: Won't that be too slow?

Alias search should respect language

• Right now, if you search for a word in English, and there is an alias for that word that corresponds to a French page, the alias will be listed.
• The list of aliases should instead be filtered on the basis of the language of the page they refer to.

Create all terms in a same category called Term

• Terms should all be created in a same categorry called Term. Search and page creation form for the Terminology module should use that category. Make the seeded pages in the profile part of that category.
• Note: The list of aliases should be filtered, so that we onlyh show aliases for pages that are in that category.

Put a new users dashboard for admins, so they can move new users to the Editors group.
