# Create a New Map {% embed url="" fullWidth="true" %} ## Create Map After logging in, you can create a new map by clicking the "Create map" button.

This will open a dialogue to allow you to define and upload the metadata for the map (e.g. title, version, source, target, etc)

## Select Author Mode First, you need to state the author mode for your project. This can't easily be changed once the map is created. When creating a new map, choose the author mode that best fits your workflow: * **Single Author Mode** : In this mode, one person is responsible for mapping, and a separate reviewer will review and validate the mapping. * **Dual Author Mode** : Two mappers work independently (blindly) on the mapping process. If they select different targets, a reconciler will review and resolve any discrepancies.
## Specify Map Metadata Next, you need to define the key metadata for your map: * **Title** : Provide a descriptive name for the map (e.g., *Example Map*). * **Version** : Assign a version number to track changes (e.g., *0.1*). * **Description** : Briefly explain the purpose of the map (e.g., *An example map from common diseases to SNOMED CT*). * **Source Code-Set** : Upload the source code set to Snap2SNOMED and select the relevant dataset (e.g., *Common diseases: 1*). * **Target SNOMED CT Version** : Choose the SNOMED CT version you are mapping to (e.g., *International Edition, 20210731*). * **Scope of Map Target** : Define the scope of the SNOMED CT target concepts: * Select from a predefined set (e.g., *Clinical Finding hierarchy*). * Use a custom Expression Constraint Language (ECL) query for a more specific scope (e.g., *< < 404684003*).

Once you have filled in all mandatory (*) fields, click the "Save" button to create your new map.

## Select Individuals and Specify Roles In this step, assign roles to team members based on their responsibilities in the project: * **Owner** : Has full control over the project, including managing roles, creating new versions, and handling project settings. * **Member** : Can author mappings, review and reconcile differences, and create tasks. * **Viewer** : Has read-only access and can view the project but cannot make changes. **How to Assign Roles:** 1. Search for an individual in the list. 2. Select their role from the dropdown menu. Proper role assignment ensures clear responsibilities and effective collaboration within the projec
