eccenca DataIntegration v23.2.1¤

We’re excited to bring you the latest update to DataIntegration v23.2, featuring numerous enhancements, bug fixes, and deprecations.

v23.2.1 of eccenca DataIntegration ships the following improvements and fixes:

  • Added overview listing all available keyboard shortcuts, available by ? key, or from the user menu.
  • Improved vocabulary (needs to be installed separately).
  • The file API will set the content type based on the file extension:
    • For instance, for a file ending in .json the Content-Type header will be set to application/json.
  • Upgraded several libraries to fix vulnerabilities.

v23.2 of eccenca DataIntegration adds the following new features:

  • User-defined project variables:
    • Can be used in dataset and task parameters and in the template transform operator.
    • Variables may use templates that access other preceding project variables or globally configured variables.
  • All new transform evaluation UI.
  • All new reference links view.
  • Extensions to transform rule and linking rule editors:
    • Support for setting a language filter for a path operator conveniently without having to use the language filter syntax.
    • Partial linking and transform rule (tree) evaluation.
  • Support fixing tasks that have failed loading:
    • Allow a user to reload a task. The user may change the original parameters of the task.
    • POST /api/workspace/projects/{projectId}/reloadFailedTask endpoint that reloads a task with optionally updated parameter values.
    • GET /api/workspace/projects/{projectId}/failedTaskParameters/{taskId} endpoint that fetches the original parameter values of a failed task.
  • Added “Concatenate pairwise” transform operator.
  • Make transform suggestion matching link spec / workflow customizable.
  • API extensions:
    • Transform evaluation endpoint: /transform/tasks/{projectId}/{transformTaskId}/rule/{ruleId}/evaluated
    • Added endpoints for uploading and downloading files of datasets.
    • REST endpoint to fetch dataset characteristics.
      • GET /api/workspace/projects/(projectId)/datasets/{datasetId}/characteristics
    • API endpoint to fetch IDs of file based datasets.
      • /api/core/datasets/resourceBased
    • REST endpoint to copy an arbitrary linking task to the matching linking task that will be used in the mapping suggestion.
      • POST /ontologyMatching/replaceOntologyMatchingLinkSpec
      • Both matching.external.projectId and matching.external.linkSpecId must be configured
    • REST endpoint that generates an ontology matching project and linking tasks based on a specific transformation task.
      • POST /ontologyMatching/generateMatchingLinkRule

v23.2 of eccenca DataIntegration introduces the following changes:

  • Close user menu automatically.
  • Linking rule config:
    • Add ‘Inverse link type’ parameter that defined a URI that is generated from the target to the source resource, i.e. the inverse of the ‘link type’ parameter.
    • Add ‘Is reflexive’ parameter that when enabled does not link resources with themselves.
  • In a workflow datasets with schema-less inputs, e.g. workflows, other datasets, are not considered to be outputs datasets anymore.
  • Variable workflow API:
    • Support uploading large input files via multipart/form-data request
    • Support custom mime type “application/x-plugin-” in CONTENT-TYPE or ACCEPT in order to support all file based dataset plugins.
    • Support query parameters ‘config-dataSourceConfig-’ and ‘config-dataSinkConfig-’ to configure dataset parameters of the data source and sink.
  • Added read-only / uriProperty dataset attributes to endpoint responses.
  • forward cmem-plugin-base to v4.1.0, via base image v2.2.0
  • The handling of errors in transform rules has been aligned with what is already shown in the evaluation:
    • If a nested operator throws a validation error (e.g., if the input value is not a number for numeric operators), this no longer leads to a failure of the entire rule.
    • The error will be added to the execution report.
    • Failed operators will return no value.

v23.2 of eccenca DataIntegration ships the following fixes:

  • Excel plugins are not available (CMEM-5088).
  • Transform/linking tasks with operators that use projects resources, e.g. Excel transform, cannot be copied/cloned to other projects (CMEM-5065).
  • Using a target property ending in /valueOf for a value mapping rule breaks the mapping editor (CMEM-5059).
  • Re-configured pure input dataset in a workflow should not be seen as an output dataset (CMEM-5058).
  • Prioritized and blocking activities should be run in a fork join pool as well (CMEM-4856).
  • Workflow(s) info endpoints return error (500) when a workflow is invalid (CMEM-5099):
    • There is a ‘warnings’ property in the returned JSON that describes which information is missing and why.
  • Remove broken legacy navigation menu from client error template that is shown e.g. when a user is not authorized to use DI (CMEM-4977).
  • Mapping editor: the path suggestion that exactly matches the search query is not shown in the list of suggestions (CMEM-5084).

Migration Notes¤


We do not guarantee forward compatibility for configuration, data or projects. I.e. importing a project created with DataIntegration v23.2 into DataIntegration v23.1 (or older) might not work.

Backward compatibility will be ensured or migration paths explained. I.e. projects created with DataIntegration v23.1 can be imported into DataIntegration v23.2.

No component specific migrations are required going from 23.1 to 23.2.
