1  i2geo Annotators Manual

1.1  Introduction

I2geo is to operate in a multi-language environment, and therefore it's not possible to search for resources using keywords. This is the reason why correctly classifying resources is so absolutely crucial to i2geo's success.

Resources are described through several metadata tags; some of them are very clear and easy to understand, such as the language used by the resource, but others are a little bit more sophisticated, such as the set of competencies that the resource relates to.

In order to work as an annotator, you will need at account in i2geo, which you can get just by visiting You also have to read the Basic User Manual, available at

Before you start metadata tagging the resources, it might be a good idea to take a look at the competencies ontology.

This manual is divided in three parts:

  • a description of the metadata of resources and traces
  • instructions on how to edit the metadata of a trace
  • instructions on how to edit the metadata of a resource
  • instruction on how to use the browsing capabilities of the Competency Editor

The process required to create a resource is explained in the Basic User Manual, and so it will not be repeated here.

1.2  Metadata description

Each resource or trace has the following data:

  • Title.
  • URL.
  • Author, which by default will the i2geo user which uploads the resource, whether this is or not the actual author.
  • License, which describes how this resource can be used. You can find more information on licenses at The license can be temporarily left blank, or "under development"; but a resource will not be public until it has been set a license; that is, other i2geo members will not be able to find it or do anything with it as long as it has not been specified how it can be used.
  • Country
  • Description, which will be displayed when the mouse hovers over a list of resources.
  • Main topic. Information on available topics can be found at
  • Other Themes, or other topics (besides the main topic).
  • Language.
  • Educational level, which is a list of the courses the resources is intended to.
  • Geometry system, which indicates the software necessary to play the resource, if applicable. A list of the software systems recognized by i2geo can be found at
  • Amount, which indicates the number of distinct interactive geometry constructions on the back of the resource, if applicable.

1.3  edition of trace metadata

The traces directory is

In this page you can see a brief list of traces. You are given the options to see all the traces that you have tagged, to see all traces, and to see traces classified by topics, licenses, and software.

By clicking on a trace you can view its metadata.

Besides viewing the values of the metadata, you are given the options to return to the list of traces, edit the metadata, and duplicate the trace so that you can edit an modify a copy with a new name, leaving untouched the original trace. If you click on "edit", you will go to a page where you can modify the metadata:

Observe the "Comment" text box at the lower part of the page; you can use it to explain why you have modified any data.

When you have finished modifying the metadata, you can click on "Save and Preview" or on "Save and Continue" so save your changes. You can also go back to the traces page without saving your modifications.

1.4  edition of resource metadata

In order to modify the metadata of an existing resource, you need permission to do so; this will depend on whether you are its author, on the resource license, on the resource accessibility (public or private), and on your membership to the group which is the owner of the resource, if applicable.

There are many ways to search for a resource; if you want to edit one of your own resources, the fastest way to find it is to click on the left menu on "MY I2GEO", then on "My Contributions", then on the "Edit" button next to the resource you want to modify.

You will go to a page with four tabs: "Edit", "Information", "Comments", and "History". Click on "Information", and the page for edition of the resource metadata looks very similar to the forms that have to be filled in order to create a resource.

When you are done editing, click on the orange "Save" button at the lower right corner of the page (in case you couldn't see a scrollbar, slide down by pressing the down cursor key).

1.5  The Competency Editor (CompEd)

The Competency Editor (CompEd) is used to navigate through the competencies, and to search and select particular competencies and topics. It is an editor because it could also be used to modify the competencies and competency ontology, although, by default, annotators do not have the permissions required to do this.

The Main Menu of CompEd is at

Observe the login tab, which you would have to do if you intended to edit the competencies. This page contains a search box, two tabs for competencies and topics, and eight lists with the latest changes; namely, these lists indicate the competencies, competency processes, topics and topic groups which have been been recently modified or created.

The competencies and topics are displayed in a tree; click on a square with a "-" to open up a branch, or on a "+" to close it.

In order to search for a competency, just enter a word and click on "Search".

A list of competencies related to that word will be shown; click on any of them to see more details.

The details of a competency include:

  • name
  • date of creation and last modification
  • URL, useful to link to the page of a competency
  • translations
  • names, which come in four groups:

    • common names, which are basically synonyms;
    • uncommon names, which are synonyms not often used, or words that may mean the same in other contexts;
    • rare names, which are words that may mean the same but are used very rarely;
    • and false friends, which are misleading words that might seem related to the competency or topic but are not; this may be due to some word similarity, a faulty translation, a common misunderstanding, or any other reason.

  • topis related to the competency
  • a tree representation of where the competency is within the ontology
  • and a list of similar items.

The details of a topic are very similar:

You can click at any time on any competency or topic displayed anywhere, and in this way you can move from one general competency to another which is more particular, from a sub-topic such as "acute triangle" to a super-topic such as "triangle", etc.
