IMPLEMENTATION

A translation set is a list of translation mappings between two value sets. This is helpful if your connection sends messages with different codes or values than your organization uses. Differences in code sets (or Redox value sets) might confuse or complicate ingesting data on your side.

Instead of wasting time detangling codes, you can use a translation set to define how two value sets should map to each other. You can use translation sets to:

  • Save time: Automatically translate codes for smooth data exchange instead of manually tweaking data.
  • Get relevant data: Make sure data is delivered in a code set that’s pertinent to your context and system.

Definitions

What’s a value set?

A value set is a list of values that should be translated during the process of data exchange. A value set could be a common code set like LOINC, SNOMED, or any other you know. It could also be a custom code set that your organization uses.

You must define a value set for each system’s code set. This means you should have two value sets to make up one translation set. Essentially, there should be a value set for each code set you want to translate to or from for each system.

What’s a translation set?

A translation set is a list of individual translations between two value sets. A translation maps either:

  • one value to one value
    Example: WISCONSIN to WI

    Your connection stores an address value as WISCONSIN. Your system stores the same address value as the abbreviated WI. A translation can resolve the WISCONSIN value at the specified field path to the value you use instead.

  • multiple values to one value
    Example: WISCO or WI to WISCONSIN

    Your connection stores an address value as WISCONSIN. Your system stores the same address value as either the abbreviated WI or WISCO. A translation can resolve your WI or WISCO values at the specified field path to the value your connection uses instead.

You can either build or import translations when creating or editing a translation set in the dashboard.

Mapping operations

Translations are a mapping type of operation, which is one of many operations that can be applied during log processing. Learn about operations.

After you link a translation set, we run our magic in the background so that you both send and receive data in the expected format.

Translation sets vs. Redox base config translation

Translation sets are different from Redox base configs, which include their own base translation. Our base translation provides a consistent experience for all our customers.

For each data model, you can see which fields are included in Redox’s base config translation by using the toggle for Show Translation Fields. Review Data Model API specs.

Prerequisites

  • All environment users can view translation sets. However, a user must be assigned to an engineer or a support role to manage translation sets. Learn about user roles.
  • You must have already defined two value sets either in the Redox dashboard or in a CSV file (must have at least 25 defined values) to create a translation set. Learn how to create value sets.

View existing translation sets

  1. Log in to the Redox dashboard.
  2. From the side nav menu, click the Operations drop-down.
  3. The Operations options expand. Click the Translations option.
    The Translations option is a sub-option under the Operations tab.
    Translations in the side nav
  4. By default, the Value sets tab opens. Click the Translation sets tab.
  5. Any existing translation sets in the environment display. To see details of a specific translation set, click the three-dots icon.
  6. From the drop-down menu, click the View option.
  7. The translation set’s details page opens.

Create a translation set

Follow the instructions to view existing translation sets.

On the Translation sets tab, click the Create translation set button to open the wizard. The instructions below take you through each step of the wizard.

Step 1: Name your set

  1. Enter a unique human-friendly name up to 500 characters (names must be unique within the environment). Then click the Next button.
    A user enters a name for the new translation set.
    Name a translation set

Step 2: Setup details

  1. You can either build translations from existing value sets in the Redox dashboard or import value sets with translations defined in a CSV file.

Step 3: Set up translations

  1. The default directionality and the selected value sets appear at the top of the tab. <Learn more about directionality>.
  2. From the drop-down fields, select the values to map to each other, then click the Add button.
  3. Repeat the previous step for each translation you want to create (up to 5,000 translations). The translations appear in the table.
    "In use" values and directionality

    An in uselabel appears next to any FROM value that has already been selected. You cant map a FROM value more than once. However, you can map multiple FROM values to the same TO value. This changes the directionality to uni-directional.

    A user maps values together, which populates the table with all the translation mappings.
    Add translations
  4. Translation sets are case sensitive by default. If your data won’t be consistently cased, toggle the Case sensitive option to OFF. This is helpful to avoid creating unique translation sets just for differing cases. If you turn off case sensitivity, any value that matches a FROM value, regardless of casing, will be translated to the indicated TO value.
    The case sensitive toggle is on the top right of the translation mappings table.
    Case sensitive option
    Disabled case sensitive option

    You might see the case sensitive toggle disabled. This happens when:

    • There are at least two FROM values that would match without case sensitivity (e.g., WISCONSIN and wisconsin). Remove any conflicting FROM values to enable the case sensitive toggle.
    • The translation set has at least one TO-FROM link, and there are at least two TO values that would match without case sensitivity. Remove any TO-FROM links or duplicate TO values to enable the case sensitive toggle.

  5. Review the table with your translations and make any changes.
    1. To edit a translation, click the pencil icon on the right. Select the correct values from one or both of the drop-down menus.
      A user edits the selected TO value for a translation.
      Edit a translation
    2. To delete a translation, click the minus icon on the left. This only deletes one translation in the table, not the entire translation set.
      A user deletes one translation from the translation mappings table.
      Delete a translation
  6. Click the Create set button.
    A user creates the translation set and its settings page opens.
    Create translation set
  7. Follow the instructions to link the translation set to apply these translations to your traffic.

To apply a translation set, you have to link it to the relevant log processing stage and field path.

  1. Follow the instructions to view existing translation sets.
  2. Find the translation set you want to link. Click the three-dots icon.
  3. From the drop-down menu, click the View option.
  4. The Settings page opens. Under the Links section, click the Link set button.
    A user finds the correct translation set to link.
    Link a translation set
  5. Follow the instructions to complete each step of the translation set wizard.

Step 1: Select translation set

  1. The translation set wizard opens. The Set name drop-down automatically populates with the translation set you selected on the previous screen.
  2. If needed, select a different translation set from the drop-down.
  3. Click the Next button.

Step 2: Select subscription

  1. For a bi-directional translation set, two options display for directionality. You must create two separate links—one for each direction—if you want a translation set to be applied in both directions. However, you can only create one link at a time. <Learn more about directionality>
  2. Select the radio button for the direction of this specific translation link.
    A user chooses a specific direction for the translation set link.
    Choose the link's directionality
    Uni-directional sets

    You cant link a uni-directional translation set in the TO-FROM direction.

  3. Click the Select subscription link.
  4. A modal opens with the subscriptions in your environment. Use the Search field or the Connection drop-down to narrow down the available options. Or, use the page options at the bottom of the modal to navigate through the pages.
  5. Select the radio button of the subscription you want to link a translation set to, then click the Select Subscription button.
    A user filters the connection to find the specific subscription they want to link a translation set to.
    Select a subscription
  6. An edit option appears underneath the selected subscription. In the When drop-down, select the appropriate processing location to link the translation set to. Learn more about log processing stages.
    Links and processing stages

    You can link a translation set to up to four log stages, depending on whether your organization owns both sides of the subscription (i.e., both the source and destination).

    • If your organization owns both sides of the subscription, you can link a translation set to any of the pre-processing or post-processing stages, whether inbound or outbound.
    • If your organization owns only one side of the subscription, you can link a translation set to the two log stages you own. For example, if you own the source side of the subscription, you can link a translation set to the post-processing stages, whether inbound or outbound.

  7. Click the Next button.
    A user selects the log processing stage to link a translation set to.
    Select log processing stage

Step 3: Select field paths

A field path is like an “address” for a particular field and value in the data payload. You can link a translation set to one or more field paths. This means you can use one translation set to update multiple values in a data payload.

  1. From the Field Path drop-down, select the field you want to link the translation set to.
  2. A modal opens for testing the field path and value. You can change your selection by clicking the Field Path drop-down again to view a list of fields.
  3. Once you have the correct path, use the validation tools to test your choice. Or, if you dont want to test, you can skip and proceed to the next step.
    1. Find a log payload for the subscription you want to translate. Learn more about searching for logs.
    2. Copy and paste the log payload into the Test Message section.
    3. On the right side of the modal, under Field Values, the value that displays is the one found at the field path you selected.
      No Redox validation

      Redox doesnt validate the translation set link. But this step gives you an idea of whether you selected the right field path by using an existing log payload.

  4. Click the Select Path button on the bottom right of the modal.
    A user selects a field path and validates the values from an existing log payload.
    Select and test a field path
  5. To add another field path, click the plus button to the right of the drop-down field. Repeat the field path steps for as many field paths you want to include in the translation set link. This is what allows a translation set to alter multiple values in one data payload at a time.
    The plus and minus icons to the right of the field path allow a user to add or remove field paths.
    Add another field path
  6. Review the information for the link. To edit any details, click the Previous button. Otherwise, click the Create Link button.
  7. The new link appears in the table and automatically applies to the linked subscription’s traffic.
    A user creates a translation set link, which appears in the translation set's settings page.
    Click the Create Link button
    Operation details in logs

    If a log has used any custom operations, you can view the related operation details when you click the related processing stage. Learn about data operations and:

  8. You can link the same translation set multiple times. To create another link, click the Link set button to repeat the process.

Edit or delete a translation set

  1. Follow the instructions to view existing translation sets.
  2. Find the translation set you want to edit or delete. Click the three-dots icon.
  3. From the drop-down menu, click the relevant option.
    1. Select the Edit option.
      Editing promoted assets

      You cant edit production assets if theyve been promoted from staging. First edit the asset in staging, then re-promote to production.

      1. The translation set wizard opens. Add, edit, or delete translations in the set.
        Edit values in a translation

        Remember to edit a value set first if you need to edit specific values in a translation. Learn how to edit a value set.

        Changing directionality

        A translation set is bi-directional by default. However, a bi-directional set changes to uni-directional if you add at least two mappings with the same TO value. You must remove any TO-FROM links first, though, since you can’t have TO-FROM links with duplicate TO values.

        To change a uni-directional set back to bi-directional, you must remove all mappings with duplicate TO values.

      2. When you’re finished, click the Update set button.
        Edit, add, or delete a translation
        Edit, add, or delete a translation
        Inactive value sets

        A translation set may point to an inactive value set version. However, once you edit an active translation set, it will automatically point to the latest active version of value set(s). In other words, you can’t edit an active translation set with outdated value set(s).

        If you don’t want to use the active version(s) of value sets, you can cancel out of any edits to the translation set.

    2. Select the Delete option.
      1. A confirmation modal appears. Click the Delete button.
      2. The translation set is successfully deleted.
        Delete a translation set
        Delete a translation set
  1. Follow the instructions to view existing translation sets.
  2. Find the translation set you want to link. Click the three-dots icon.
  3. From the drop-down menu, click the View option.
  4. The Settings page opens. Under the Links section, find the link you want to edit or delete. Click the three-dots icon.
  5. From the drop-down menu, click the Delete option or click the Edit option.
    Deleting a translation set link

    If you click the Delete button, a modal opens to confirm. You can delete a translation set link that’s in use. Logs will still process, but without the translation set link, no translation will occur.

  6. If you clicked the Edit button, the translation set wizard opens. Edit any of the details, then navigate through the wizard and click the Update Link button.
    A user edits the selection for the log processing stage.
    Edit a translation set link

Promote a translation set

During implementation, you can build and test a translation set in a staging environment. Once you’re confident it works, you can promote it to production.

When you promote, the value set is automatically promoted, too. Value sets can’t be promoted on their own.

Promoting an asset saves time and avoids introducing errors by having to rebuild it in a different environment. Learn more about promoting assets.

  1. Log in to the Redox dashboard.
  2. From the Environments drop-down, select the Staging environment.
    The environment drop-down field in the top left corner of the Redox allows you to switch between environments.
    Select the staging environment
  3. From the side nav menu, click the Operations drop-down.
  4. The Operations options expand. Click the Translations option.
    The Translations option is a sub-option under the Operations tab.
    Translations in the side nav
  5. By default, the Value sets tab opens. Click on the Translation sets tab.
  6. The list of existing translation sets displays. Find the translation set you want to promote. Click the three-dots icon.
  7. From the drop-down menu, click the View option.
  8. The Settings page opens. Click the Promote button.
  9. A modal appears to confirm that you’re exiting staging and proceeding to production. Click the Proceed button. Otherwise, click the Cancel button to discard the promotion.
    A user promotes a translation set and proceeds to production.
    Promote a translation set to production
  10. The Settings page in the production environment opens.
    1. To make any changes to the translation set, click the Go to Staging button.
      The Go to staging button appears on the top right of the details.
      Go to staging to edit
    2. A modal appears to confirm that you want to switch environments. Click the Proceed button to continue.
    3. The translation set settings page opens in the staging environment. Follow the instructions to edit a translation set.
    4. Once changes are successfully made, re-promote the translation set to keep the assets in sync across environments.
  11. Next, add link(s) to subscriptions to apply the translation set in your production environment.

Restore a translation set version

Every time you edit a translation set, you create a new version of the asset. You can restore a version of a translation set that’s not currently in use. This may be helpful when troubleshooting to see where an error might have been introduced or to resolve an error by using a version that worked previously.

  1. Follow the instructions for viewing existing translation sets.
  2. From the list of existing translation sets, click on the translation set you want to restore.
  3. The Settings page opens. Click the Restore button.
    A user clicks the Restore option and the diff view opens.
    Click the Restore button
  4. A modal appears to restore a version. From the drop-down, select a version to restore.
    Restore notes

    Restoring means activating a version that’s not in use. That means you can go backwards or forwards a version. However, you can’t restore a version that’s already in use.

  5. The diff view shows what’s different between the current and selected version. Review the differences, then click the Restore button.
    Versions after editing

    If you edit an asset after restoring a previously used version, a new version is created.

    For example, let’s say you were on version 3 and you restore version 2. Then you make and save edits to version 2. This creates version 4 of the asset. At that point, you can still restore to version 3 at any time.

    A user selects a version to restore and reviews the differences.
    Compare translation set versions
  6. For promoted assets, restoring a version only applies to the current environment. If you restore a version in staging, you might need to re-promote the asset if you want to apply it to production as well.
    What happens to value sets?

    If a restored translation set points to an inactive value set version, the restored translation set will continue to use the inactive value set(s). Translations will still process as defined by the inactive value set(s).

    However, once you edit an active translation set, it automatically points to the latest active version of value set(s). In other words, you can’t edit an active translation set with outdated value set(s).

    A warning appears when a user hasn't pushed changes to a promoted asset to production.
    Unpushed changes
    A warning icon appears on the translation sets table if staging and production versions are out of sync.
    Out of sync versions

Technical reference: Directionality

A translation set is bi-directional by default. This means the values can be translated in either direction: FROM-TO or TO-FROM. When you map more than one value to the same value, the translation set becomes uni-directional. A uni-directional translation set can only be linked going FROM - TO.

A translation set can be either bi-directional, or uni-directional.

  • Bi-directional (default): A translation can potentially be linked twice, meaning the translation could happen in both directions. For example, a translation that maps between Value A and Value B means that the values can be translated on both sides of the exchange, back and forth.
    Bi-directional translation set linked to two log processing stages

  • Uni-directional: A translation can only be linked once going in one direction. This works for translating one value to one or multiple values to one. For example, if you have a translation from Value to Value B, the translation happens only once and won’t be translated back. Specifically, Value B wouldn’t ever be translated to Value A. You could also have a translation from Value A or Value C to Value B.
    Uni-directional translation set linked to one log processing stage
    Uni-directional translation set linked to one log processing stage

A translation set automatically changes from the default bi-directional option to uni-directional if you add translations for multiple values to the same value. This can only happen if you don’t have any other bi-directional links, however. To change a uni-directional set back to bi-directional, remove all translations with mappings to the same value.
