Tasks of the Workgroup

The workgroup helps to realize the POC 1 - POC 3 from the roadmapV1
Analytical approach to improve the standard data model (configuration)
- Evaluating the standard data model by comparing it to existing standards (EDIFACT, BiPRO, InfoSphere, etc.)
- Deriving mapping rules to map the "OIH standard" against existing Standards
Technical implementation is done by the architecture workgroup. See repository architecture workgroup
Rules and regulations of the data models
- How do the data models evolve? What is the process to decide on suggested changes (Versioning) - for example?
- How shall new data models be developed
Documentation for the implementation of transformer (mapping)
The workgroup helps to achieve the results of milestone 2 by contributing to the "Access to the OIH platform 0.5" and "Document procedure model for integration cloud provider"

Presentation of the results for milestone 1
Derived information for the architecture workgroup: The architecture must consider that multiple data models (will) exist

Currently the POC 1 is not finished because the integration between SilverERP and Snazzy Contacts is not working
Difference between POC 1 and POC 2 is the application of the adapter quality guidelines on the SilverERP and Snazzy Contacts adapters
A documentation of the current status of POC 1 is missing yet (See derived tasks)
Documentation of the meta models is not part of the API

See the current status of the specs under DataHub.md

Raw data is syntactically transformed data
Decoupling between adapter and transformer
- Adapter can talk to the transformer and/or to other adapters. Thus semantic transformation via the transformer and individual integrations are enabled
- (Adapter holds syntactically transformed data). Not mandatory: ISV doesn't have to upload the data into the raw data storage.
Meta Data Management API uploads the information about the metadata (list of objects)
Data Management API uploads the actual data (data records)

Within the scope of this topic the following illustrations was drawn:

Synchronization of roles & rights / user & user roles has to be enabled by the open integration hub. It will most likely be realized by an additional domain such as addresses and products
- The identities Basaas wants to synchronize are not stored within the identity management but will be realized through the aforementioned additional domain
Various aspects of the synchronization of user & roles are needed. See derived tasks "exchange ideas regarding the synchronization of user & roles"
Distinction between identity management of the open integration hub (minimal functionality to manage identities) and the domain "roles & right / user & roles"

Elaborate common structure for the documentation of the standard data model (JSON-Schema, UML diagrams, textual description) Raphael + Lutz
Expand and further describe the superordinate structure for the domain models (see OIHDataRecord) Raphael + Lutz
Elaborate/expand rules and regulations for the evolution of standard data models (How do the data models evolve?, How shall new models be created, how often are new versions created, ...) Raphael + Lutz
Consider the "Meta-Meta Model" (Definition used by Renat) with respect to the capabilities of the JSON Schema (E.g. types like date, currency, etc.)
Compare the standard data model (configuration) with existing standards (EDIFACT, BiPRO, InfoSphere, etc.) Raphael
Document the current status of the POC 1 (The following steps break down the concrete tasks) Andy + Josef
- Provide an API documentation / interface documentation - public
- Create JSONata expression (mapping)
- Create a mapping table
- Document which elastic.io components where used and why
- Compare the documentations of YQ and Wice and unify them
For POC 2: Apply the adapter quality guidelines on the adapters by YQ and Wice Philipp
Decide on technical realization of the connectors Franz
(Technical) realization of the integration node from POC 2 Franz + Igor
(Technical) realization of the smart data framework with master data management (mdm) Franz + Igor
Exchange ideas regarding the synchronization of user & roles Lutz + Selim
