Service

A Service is an independent, Dockerized program capable of processing data. It can be of two types:

• Batch: It is started, processes data, and terminates its execution.
• Streaming: It is started and processes data for an indefinite period until the Workflow containing it is interrupted.

A Service is characterized by:

• I/O Ports
• User-configurable execution parameters

I/O Ports represent the input and output interfaces of the Service, and allow it to interact with other ALIDA Assets (Datasets, other Services, Models) within a Workflow.

Management of Services

The ALIDA catalog natively includes a series of ready-to-use Services for the creation of Workflows.

For information on how to create custom ones, visit Creation of a Service

To access the Service management page, access it from the sidebar menu as shown in the following figure:

^{View services from the sidebar menu}

^{View the list of services}

Once you have reached the page, you will find the list of Services.

From the top bar, it will be possible to:

^{Service search filters}

• Access the Service registration form
• Search for Services
• Filter by framework
• Filter by tag
• Filter by categories
• Show only "My Services"
• Sort the Services
• Change page

From each Service card, the following functions are also available:

Cloning a Service

Clicking on will create an independent catalog copy of the Service in question.

Editing a Service

Clicking on will allow you to modify some of the metadata of the Service, such as:

• Name
• Description
• Category
• Service Tags
• Documentation in Markdown

^{Service registration/editing form}

Deleting a Service

Clicking on will allow you to delete the Service from the catalog.

Assigning the Service to a Project

Clicking on the card of a Service will open its detail page, from which you can access the Manage Projects function .

A dropdown menu will open and you will be able to choose a Project to add the Service to.

^{Select project to add the service to}

Annotating Services

Within the Workflow Designer, it is possible to associate a set of structured annotations with each Service component of the Workflow.

These annotations must previously be defined by an administrator from the Control Panel (see Definition of Annotations)

To annotate a Service:

1. Open the Workflow Designer for the desired Workflow

2. Click on the Service to be annotated and then on Notes on the right

   ^{Choose service annotations from the Designer}

3. In the dialog that opens, click on and select the desired annotations from the dropdown menus:

   ^{Assigning annotations}

4. Finish by clicking on Save

Once finished, it will be possible to:

• View the inserted annotations
• Delete them
• Add other annotations
