User stories
| Info | ||
|---|---|---|
| ||
Requirements are based on a user story, which is is an informal, natural language description of one or more features of a software system. User stories are often written from the perspective of an end user or user of a system. Depending on the community, user stories may be written by various stakeholders including clients, users, managers or development team members. They facilitate sensemaking and communication, that is, they help software teams organize their understanding of the system and its context. Please do not confuse user story with system requirements. A user story is an informal description of a feature; a requirement is a formal description of need (See section later). User stories may follow one of several formats or templates. The most common would be: "As a <role>, I want <capability> so that <receive benefit>" "In order to <receive benefit> as a <role>, I want <goal/desire>" "As <persona>, I want <what?> so that <why?>" where a persona is a fictional stakeholder (e.g. user). A persona may include a name, picture; characteristics, behaviours, attitudes, and a goal which the product should help them achieve. Example: “As provider of the Climate gateway I want to empower researchers from academia to interact with datasets stored in the Climate Catalogue, and bring their own applications to analyse this data on remote cloud servers offered via EGI.” |

US1 | US2 | ...The project goal is to deploy a DevOps environment, with necessary capacity of Cloud Infrastructures and services for testing ENVRI-FAIR development. The project aims to automate the testing/integration of the FAIR data services developed by the teams in ENVRI-FAIR. |
Use cases
| Info | ||
|---|---|---|
| ||
A use case is a list of actions or event steps typically defining the interactions between a role (known in the Unified Modeling Language as an actor) and a system to achieve a goal. Include in this section any diagrams that could facilitate the understanding of the use cases and their relationships. |
Step | Description of action | Dependency on 3rd party services (EOSC-hub or other) | |
|---|---|---|---|
UC1 | Automated Cloud execution for data workflow : In VREs, scientific workflow (including workflow logic, services, and data objects) need to be executed in Cloud environment dynamically at runtime. The VRE needs to automate those steps: virtual infrastructure (networked VM) provisioning, software deployment (Dockers or RESTful services), workflow execution, runtime monitoring, and provenance. | EGI Cloud Compute | |
UC2 | Continuously testing and integration for ENVRI services: ENVRI Knowledge Base ontology/demonstrator are described as RDF files in the git repositories, each update will trigger an automated testing/integration activities via the DevOps pipeline | Jelastic PaaS EGI Dynamc DNS | |
UC3 | Notebook based environment for FAIR data access and processing: ENVRI users (users of RIs/VRE) will perform their scientific research using data, software service and models. .. | ...They often perform such kinds of activities using Jupyter notebook. | EGI Notebooks ( Community instance) EGI DataHub |
