Services
- All Services
- Node
  - Set Node
    Set a node, i.e. create or update it, or retrieve information required to create or update it.
  - Get Node
    Get a version of a node.
  - Delete Node
    Delete a node version and everything that depends on it. If this is the only version, delete the node.

    Change the owner associated with a node.
  - Node Import
    Node import is a flexible, high-performance service for loading data into Advisor.
  - Node Export
    Export nodes.
  - Get Changed Value
    Get the value of a member, but only if it has changed since it was last retrieved.
    This is used as a quick way of retrieving a piece of data, but bypassing the read if the data has not changed since the last read.
    Call the service passing it a node version reference for the node, one for the member type, and optionally a timestamp when it was last retrieved or updated.
    If the data has changed since the timestamp, the service will return changed of true, timestamp set to ...
  - List Nodes
    Return a list of node versions.
  - List Node Versions
    Lists all the versions of a node.
  - List Recent Node Types
    List the node types that the user has used recently.
  - List Contained Node Types
    List the node types that are in use within a package.
  - Update Node Versions
    The Update Node Versions service creates new versions of nodes which link to new versions of node types and member type targets, to update a node structure to later node versions.
  - Freeze Node
    Freeze a node version, and all the draft node versions on which it depends, i.e. the node version of its node type and all its target nodes.
- User
  - Create User Extended
    Create a user.
  - Get User
    Retrieve information about a user.
  - Get User Details
    Retrieve information about a different user. The user making the call is identified as usual using the userLogonReference. The user about which details are to be returned is specified in userLogonReferenceDetails.
    The user running the service must be able to grant to the user, e.g. they must be the user, or have maintain-users permission, or own-users permission.
    This is similar to GetUser, but GetUser is used for sign on processing and only returns details of the user ...
  - Get Home Node
    Return the home node for the current user.
  - User Exists
    Indicates whether a user or user group already exists.
  - List Users
    Return all the user groups and all the users to which the current user is authorised to grant, or, on the case of users, authorised to include in user groups.
  - User Search
    Search for a user.
  - List Owned Users
    Return all the users over which the current user has own-users authority.
  - List Users By Email
    Lists users for a given email address.
    This is intended to be used by a sign-in helper script. It returns the response in JSON format.
  - Update User
    Update user information, i.e. name and email address.

  - Change User Owning Group
    Change the owning user group for a user, i.e. move them from one owning user group to another.
    The caller must have authority to maintain the user and must have own users authority on the new group, the same permissions they would need to delete and user and create a new user in the to user group.
  - Create Session
    Creates a Metrici session.
  - Create Proxy Session
    Creates a proxy user session within a given account. The session token and a client session token are returned.
    It does not create a proxy session if:
    - The caller is not authorised.
    - The account identifier is not passed or does not exist.
    - The caller does not have a proxy user in the account.
  - Query Session
    Determine if a session token is still valid.
    This does not sign in with the session token. Single use session tokens are not consumed by using this.
  - Cancel Session

- User Group
  - Create User Group
    Create a user group.
  - Get User Group
    Return details of a user group and its members.

  - Change User Owning Group
    Change the owning user group for a user, i.e. move them from one owning user group to another.
    The caller must have authority to maintain the user and must have own users authority on the new group, the same permissions they would need to delete and user and create a new user in the to user group.
  - Delete User Group
    Delete a user group.
- Permission
  - Create Permission
    Create permissions.
  - Get Permission List
    List the permissions the user is authorised to maintain and create.
  - Delete Permission
    Delete a permission, using the permission id.
  - Refresh Manifest Permissions
    Refreshes the permissions defined on a manifest.
- Security
  - Run Authorized
    Run another service, after checking that the user has submit service authority.
  - Hash
    Returns a secure one-way hash of a string.
    It is astronomically improbable that two strings have the same hash, or that a string can be derived from a hash by brute force.
  - User Hash
    Returns a secure one-way hash of a string in a way that only the user can calculate. Use this so that a user can "sign" a string and later check that it has not been modified.
    It is astronomically improbable that two strings have the same hash, or that a string can be derived from a hash by brute force.
    The hash is sensitive to changes in the user setup, such as password change, so this should only be used for hashing strings as part of a short-term process.
    Use ...
  - Generate Keys
    Generates a public/private key pair, using the RSA algorithm, and 2048 bit encryption.
    Keys are returned in privacy enhanced mail (PEM) format.
    This is a very simple service. It requires no authorisation, and it returns no errors.
  - Create JWT
    Create a JSON Web Token (JWT), signed with a private key. The private key should have been generated with the GenerateKeys service, and is passed in as a PEM-format PKCS#8 encoded string.
  - Verify JWT
    Verify a JSON Web Token (JWT).
    The JWT is verified against a public key passed in as a PEM-encoded string.
    In addition to verifying the JWT signature, the service performs the following checks:
    - That the jwt has not expired. If passed, the clockSkew value can be set to a number of additional seconds to allow an expired token, to make up for clockSkew, or for the time taken for a token to be passed to a service.
    - The the JWT "aud" claim, if present, ...
- Theme
  - Get User Theme
    Return theming details for a user and/or a domain.
  - Get Themes
    List the themes available to a user.
- File handling
  - Read User File
    Read all of the data in a user file and return it as a block of text. Optionally can access an entry within a zip file. Can return plain text or base64.
    The service runs without authority; if a user knows the storage key they are presumed to have authority to read the file.
  - Write File
    Write data out to a user file.
  - Get User File Info
    Returns information about a user file identified by a file storage key.
    
    By default this returns only an error number to indicate if the file storage key is valid and, if it is valid, the size of the file.
    
    Set the parameter contentType to true to return a contentType for the file.
    
    Set the parameter digest to a digest method (such as MD5) to return a digest of the content of the file. The list of permissible methods is available in the "MessageDigest ...
  - Resize User File Image
    Resizes an image held in a user file.

    - HTTPS and port specification.
    - Authentication
    - Parameters
    - Headers

Having decided the purpose of the assessment, the next step is to decide precisely what is going to be assessed by whom.

The evaluand is the thing being assessed. It could be "The Organisation", "Customer Service", "Project Phoenix", "42 Acacia Avenue", "Today's Weather", and so on.

Each person who completes the assessment is known as a respondent, or a contributor.

You need to think about:

Is there one evaluand (such as the organisation) or many (such as the projects run by the organisation)?
If there are many evaluands, are they all of the same type (for example, they are all projects), or many types (projects, staff, teams and computer systems).
Is there a single assessment of each evaluand, or do multiple people each give their opinions of the evaluand?
Is the entire assessment of each evaluand carried out by a single person, or do different people contribute to different aspects of the assessment?
Is the assessment carried out by people who are responsible for the evaluand (a self-assessment), by others (an independent assessment), or both (a self assessment that is then independently assessed).

Assessments can be repeated. Initially think about the evaluands and respondents for each run of the assessment; the Process section covers repeat assessments.
