The first step is to register with a Mx (Metadata Exchange) instance, shortly after registering your administrator will send you an email notifying you of your access details.
By default there are 3 levels of access, administrator, curator and guest. The basic differences between these rights are as follows: a guest will only be able to view models, a curator will be able to create and modify models and an administrator will be able to add new users; however different Mx instances may be set up with a variety of different access levels and rights, so it is best to consult your administrator to find out what rights and capabilities you have.
Once you login you should see a screen like the one following:
Which on first sight may seem a bit daunting. So we can divide the screen into sections, as shown below:
- Home button – clicking this will return the user to this view from anywhere inside the application.
- Quick Actions – A variety of action, listed below, this include the data item search – not to be confused with the model search in 3.
- General Models Search – This is a search for data models, it does not include other data items, for everything other than data models you need the Data Element search in 2 – explained in detail below.
- Tabs between “My Models” (otherwise known as favourites) and the whole catalogue of datasets. If you use the Mx a lot then you may wish to keep your “favourite” data models here. Click on the “Favourites” button and the model will appear in “My Models” (see below)
- Create (a new model) and Import (a model) Buttons.
The buttons in the right hand side (Quick Actions) grouping are:
Data Element Search - 
Button 
Click on this to and a new (search) screen will pop up, in which you can search for any data element, either in the current model or in any other model. This is the search for data items rather than complete models, in fact this search indexes all other metadata items in the Mx : Data Elements, Data Classes, Data Types, Assets, etc…and you can configure it to point at the current Data Model or include all Data Models in the Metadata Exchange.
Fast Actions - Button
Fast Actions - Click on this to get a selection of actions - this menu may vary depending on your configuration. In the illustration the menu which appears will enable the following actions : Activity (admin only - enables an admin user to see recent activity in the Mx), Import Catalogue XML - enables a user to import an XML dataset, Import Excel/Loinc/MC/OBO/Rare Disease CSV / Star UML - a variety of model imports from different file types. Model Catalogue version - see exactly which software version is being used, Show all Models - defaults to focus on the My Models list of datasets.
Curator - -This is a menu for data curations, consisting of the same
Admin - -
User - -Each button will trigger an action that we detail in later sections.
