Corporate Memory 21.11¤

Corporate Memory 21.11 is the fourth release in 2021.

21.11 - workflow editor - inline (live) progress and statistics

21.11. - Explore - custom graph lists as well as new look and feel

The highlights of this release are:

  • Build: The workflow editor user interface allows for undo/redo of you activities now, as well as shows inline (live) progress and statistics of a running workflow.
  • Explore: The Explore interface is now adapted to our new look and feel + the Knowledge Graph list component can be configured to show multiple lists of named graphs e.g. to distinguish between user, vocabulary and system graphs.
  • Automate: cmemc can now interact with workflow scheduler (disable, enable, inspect, list, open) as well as dataset resources (delete, inspect, usage, list).


With this release of Corporate Memory the DataIntegration and DataPlatform configuration and behaviour has changed and have to be adapted according to the migration notes below.

This release delivers the following component versions:

  • eccenca DataPlatform v21.11.1
  • eccenca DataIntegration v21.11
  • eccenca DataManager v21.11.5
  • eccenca Corporate Memory Control (cmemc) v21.11.4

More detailed release notes for these versions are listed below.

eccenca DataIntegration v21.11¤

This version of eccenca DataIntegration adds the following new features:

  • Remote Excel Dataset using Google Drive Spreadsheets as resources.
  • Remote Office 365 Spreadsheets Support.
  • Workflow editor improvements:
    • View navigation via clicking and dragging the mouse on the mini-map.
    • Config input port is hidden by default and can be enabled via menu entry.
    • Inline (live) progress and statistics.
  • Support mapping of RDF literals in object mappings.
    • Literals are handled as entities and can be mapped in object mappings.
    • Special path #text that allows to access the lexical value of the mapped resource. This allows to access the value of a mapped literal in an object mapping.
  • RDF datasets:
    • Special path #lang that allows to access the language tag of a language tagged RDF literal.
  • Extensions to the Excel dataset:
    • Excel columns may be addressed by their letter code (#A, #B, etc.) as well.
    • A new parameter ‘hasHeader’ allows handling of pure data sheets with no table header.
  • Support selecting multiple vocabularies with auto-completion support.
  • Transform URI pattern improvements:
    • Validation of URI patterns in the UI and backend, i.e. it checks that URI templates generate valid URIs.
    • Auto-completion support in URI pattern input component.
    • URI pattern validation endpoint
    • URI pattern auto-completion endpoint
    • Change initial URI pattern of complex URI rules from / to {}/<OBJECT_RULE_ID>
  • REST endpoint to fetch an activity execution error report as JSON or Markdown.
  • Activity integration into task detail pages:
    • Primary, running, failed and all related caching activities are shown on the task detail pages.
    • Caching activities are grouped and have additional information and controls like ‘refresh all caches’, last update etc.
    • For failed activities it is possible to see and download an execution error report.
  • Support for requesting task parameter values in the item search API.
  • New workflow operator to stop the current workflow execution (without failing) if a specified condition has been met.
    • Add global cache for URI patterns that stores all URI patterns extracted from transform tasks.
    • Add API endpoint to fetch all URI patterns used for given target class URIs.
    • Allow to select from existing URI patterns (related to the same target classes) in object mapping rule form.
  • Support setting the URI pattern during creation of an object mapping rule.
  • Application version info in user menu (sidebar on the right side).
  • JDBC dataset does support token-based authentication for MS SQL server now.
  • Undo/redo support in workflow editor.

In addition to that, these changes are shipped:

  • Improved task search with highlighting for nodes in the canvas.
  • Added “Default Value” Transformation to recommended category.
  • OLE2-based Excel documents (e.g., .xls) are now supported in non-streaming mode.
  • Enabled the Excel ‘LEFT’ transform function.
  • Mapping Rule Editor will show the rule label (if any) and the mapping target.
  • The JSON dataset supports streaming.
    • The change applies to reading JSON, writing was already streamed.
    • If streaming is enabled, files won’t be loaded into memory, allowing to read large JSON files without running into OutOfMemory errors.
  • Allow to open the value mapping rule formula editor from the create/edit value mapping rule form.
  • Improvements to Template operators:
    • Added option to forward input attributes.
    • Allow tests in conditions (e.g., if input1 is sequence).
    • Updated Jinja library to latest bugfix release.
  • Render markdown (links only) in meta data preview and search item description instead of markdown markup text.

  • JDBC dataset will retry failed queries due to interrupted connections. Retries will start at the offset of the previously read row.
  • Include query URLs in result from REST operator (multi input).
  • Workflow editor: Adapt node height based on number of inputs.
  • Project import does not show the error message.
  • Added rail navigation bar, replacing the old navigation.

In addition to that, multiple performance and stability issues were solved.

Migration Notes¤


  • The fix of ‘XML dataset ignores base path when type URI is set.’, could break existing projects that are relying on the previously broken behaviour.
    • This may affect all use cases with XML datasets that have the ‘base path’ parameter set to a non-empty value AND where a transformation or linking task overwrites this path by setting a type path/URI.
    • Removing the ‘base path’ value from the affected XML datasets should solve the issue.
  • Generating URIs for entities failed if XML tags contained dots
  • The JSON dataset uses streaming by default now, which does not support backward paths.
  • Using backward paths will fail and the error message will contain a suggestion to change the streaming parameter to false.


No migration notes


  • Jinja templates will no longer fail on unknown tokens. If this was used for signaling errors or fail-fast evaluation, this has to be implemented in regular conditional checks.
  • Virtuoso config requires adjustments, its HTTP port needs to be configured.
    • Please ensure, that the configured user has the same access rights in virtuoso via ODBC and HTTP
