My normal user and password does not work on CompEd, why?

CompEd and i2geo do not use the same user pool, for various technical reasons.
Please request another account on . You are strongly advised to use the same user-name and passwords so that stored passwords in your browser do the right thing.


I have registered to CompEd but I cannot change anything!

This is a normal security policy… we wish to give unknown users gradual change rights while project partners should receive full curriculum-encoders' rights.
Once you have created a user, please send a user-name and some details about you to


When are my changes visible?

CompEd is an editor, it displays the changed competencies and topics right away and sends update events.
The events are visible in the ontology snapshot within a few minutes and should be visible in all skills-text-box instances as well (annotation, search (soon), or in the debug skills-text-box ).


What is a curriculum text?

If you are a curriculum encoder or translator you are most probably based on a text describing the contents of the curriculum standard: this can be either the legal text but could also be a text book.
A recommended workflow of the curriculum encoder is to go through these documents and hyperlink relevant sentences. We try to publish these documents on the web (click the Curriculum-texts link below the search box on top of this page) after their conversion so that hyperlinks become "choose actions": in most cases it means to search for the linked topics and competencies.

This workflow is presented in the curriculum-linking-video.

Which document should I choose as curriculum-text?

A curriculum-text can be either the text of a curriculum-standard such as those provided by the governments, or the list competencies or table-of-contents of a textbook. The idea is that we should be able to publish such a document on the web, in a browser-browsable form with links generating javascript calls.
Some of that has been described at Textbooks-as-curriculum which is document to present our ideas to publishers. HTML still is the only supported format.

What hyperlinks should I insert into curriculum-texts?

The links should be simple href attributes containing a space separated list of URIs.

Several type of URIs will be supported by the curriculum-text-transcoder, including #fragmentID and the OWL URI as well as the link that CompEd gives you to preview a topic or competency. The latter is probably the easiest to check.

Once you are, even partially, done, please commit the curriculum-text, so that it is visible on and drop a mail to the message board of this group so that it is processed and becomes visible in the curriculum-texts-page.

CompEd asks me for a URI but I cannot input what I want, why?

A URI is often used in many different situations as an identifier; hence it should contain only restricted characters: letters A-Z a-z, underscore _, or dash -. CompEd enforces this and refuses a URI that has a different syntax.

So if you want to insert a note about the theorem of Rolle, your best choice is to make it Rolle_theorem.

Where do I write that this topic is for this educational level?

The educational level associated to a topic or competency is indeed a property in the ontology but it is not possible to input it in CompEd. However, the association between a curriculum text and a topic or competency is obvious, hence this property can be deduced but this has not been implemented yet.

Once this is implemented, we should be able to prefer topics and competencies that are in educational levels or educational regions of interest to the user. This is the only usage of the property that we know of.
