Modules
1. ICT Platform
The ICCS CIRC4Life ICT Platform is the main host system of the Access Control Manager, the REST Web Services and Persistent Databases. End-users and project client applications retrieve and update data by using the single authorization point provided by the Access Control Manager.
1.1 Access Control Manager
The Access Control Manager is responsible for all Authentication and Authorization of the ICT Platform. It handles the consumer’s Eco-accounts and the accessibility of 3rd party application to the provided REST Web Services. The implementation is based on the Open Source Identity and Access Management platform Keycloak, a project supported by the industry’s open source leader RedHat. keycloak uses standard protocols and provides support for OpenID Connect, OAuth 2.0, and SAML. It integrates with a large list of different technology stacks and programming languages via Client Adapter libraries. It can federate user repositories from external LDAP or Active Directory servers and also provides identity brokering for external social networks including:
1.1.1 ICT Web Services (REST)
All data access to end-users and 3rd party client application is provided by a layer of REST Web Service endpoints. The Application Programming Interface (API) provided by the REST endpoints targets to cover all System and User Requirements described in Deliverable 4.1. See REST APIs and Services Usage.
1.1.1.1 Master Product Data
See Data Models.
1.1.1.2 User Eco Account
See Data Models.
1.1.2 Data Gateway
See Data Models.
2. Data Providers
ENV developed applications for data entry input, mainly for products and their life cycle information.
2.1 Data Entry Tool for Stakeholders
Available as a Web Application here: ENV Data Entry Tool.
- Username: DataEntryTool
- Password: iccs.isense.circ4life.envirodata.2019
2.2 Intermediate Products Data Export Web Service
Available as a Web Application here: ENV Data Export Service.
No authorization is in place, the service is public.
3. Services
External Web Services, not part of the core ICT Platform.
3.2 Traceability Module
Available as a Web Application here: CIRC4Life Traceability Module.
4. End user applications
Consumer applications for mobile devices.
4.1 Eco Account and Shopping Module
Google Android mobile application. It can be installed on Android devices via the Google Play Store.
