Deployment

Agents Kit Banner

Agents KIT​

Operating federated queries over the whole data space.

Motivation & Deployment Roles​

Knowledge Agents is a federated technology, so there is no central component setup to take into account. Instead, the Semantic Dataspace is formed by the individual business partners extending/configuring their connectors and enabling their backend systems and/or datalakes. The deployment depends hereby on the role that the business partner takes. The roles are described in more detail in our Adoption guideline.

Dataspace Roles

Role: As A Consumer​

As a consumer, you just need to:

  • enable your dataspace connector to initiate/delegate the required Agent protocols (here: SparQL-over-Http).
  • (optionally) use a separate matchmaking agent to securely host your own business and meta data in the graph storage behind the connector layer
  • (optionally) mount your matchmaking agent as a remote repository into your enterprise graph infrastructure.

Role: As A Skill Provider​

As a skill provider, you need to

  • enable your dataspace connector to transfer/delegate the required Agent protocols.
  • (optionally) employ multiple data planes in case you want to expose hosted skills (skill assets that operate as stored procedures and which require computational resources at the provider side) instead of distributed skills (skill assets that are offered as query texts/files and which are executed at the consumer side).

Role: As A (Data/Function) Provider​

As a provider, you need to

  • enable your dataspace connector to receive/internalize the required Agent protocols.
  • (optionally) use a separate matchmaking agent to securely publish your own business and meta data from the graph storage behind the connector layer

Depending on the kind of provisioning, you will setup additional internal "agents" (endpoints).

Sub-Role: As A Data Provider​

As a data provider, you want to

  • bind your data sources to knowledge graphs following the Catena-X ontology. Therefore, a provisioning agent should be setup on top of a data virtualization/database layer.

Sub-Role: As A Function Provider​

As a function provider, you want to

  • bind your API to a special knowledge graph structure. Therefore, a remoting agent should be setup.

Sub-Role: As A Twin Provider​

As a twin provider, you want to

  • bridge between the Knowledge Agent and Asset Administration Shell APIs.

Runbook For Deploying and Smoke-Testing Knowledge Agents (Stable)​

The Stable Environment is a minimal example environment exhibiting all roles and capabilities of the Tractus-X/Catena-X dataspace.

Knowledge Agents on Stable is deployed on the following two tenants

  • App Provider 1 (BPNL000000000001)
    • Dataspace Connector (Postgresl, Hashicorp-Vault) "provider-connector" see manifest
    • Agent-Plane (Postgresql, Hashicorp-Vault) "provider-agent-plane" see manifest
    • Provisioning Agent incl. Local Database "sql-agent" see manifest
    • Remoting Agent (against a Public WebService) "api-agent" see manifest
    • AAS Bridge (against a prerecorded )"aas-bridge" see manifest
  • App Consumer 4 (BPNL0000000005VV)
    • Dataspace Connector (Postgresl, Hashicorp-Vault) "consumer-connector" see manifest
    • Agent-Plane (Postgresql, Hashicorp-Vault) "consumer-agent-plane" see manifest
    • Matchmaking-Agent "consumer-agent" see manifest

1. Prepare the Two Tenants​

As a first step, two technical users are installed for the dataspace connectors using the https://portal.stable.demo.catena-x.net

  • App Provider 1: sa4
  • App Consumer 4: sa5

The generated secrets should be installed under https://vault.demo.catena-x.net/ui/vault/secrets/knowledge

  • stable-provider-dim
  • stable-consumer-dim

Further secrets should be installed

  • oem-cert
  • oem-key
  • oem-symmetric-key
  • consumer-cert
  • consumer-key
  • consumer-symmetric-key

Finally, an access token to the vault has been generated.

2. Deploy Agent-Enabled Connector's​

Using https://argo.stable.demo.catena-x.net/settings/projects/project-knowledge the following three applications have been installed.

We give the complete manifests but hide the secrets.

4. Deploy App Provider 1 Provisioning Agent​

Using https://argo.stable.demo.catena-x.net/settings/projects/project-knowledge the following application has been installed.

For simplicity, the provisioning agent exposes a builtin sample H2 database as a graph and therefore needs to write the file system with its non-root account. Therefore, some of the following settings are specific to stable and will not be used under productive settings.
