===== Extract Regesta Page =====

The “Extract Regesta” page constitutes the main interface of the Regexta application and is accessible to both non-authenticated and authenticated users.

The screen is structured into two main areas:

  * input area (left);
  * output area (right).

The entire regestum generation process takes place within this page.

----

==== General interface description ====

The upper part of the page presents:

  * navigation breadcrumb;
  * section title “Extract Regesta”;
  * navigation tab to the “Collections” page (visible only to authenticated users).

The central area is vertically divided into two columns.

Left column – Input

  * “Select Document Type” select (mandatory);
  * “Select Collection” select (visible to authenticated users);
  * text input area;
  * “Upload a file” button;
  * “Reset” button;
  * “Extract Regestum” button.

Right column – Output

  * “Output” section;
  * “Input Accuracy Index” indicator;
  * automatically generated structured fields (e.g. Sender, Receiver, Place of emanation, Date of emanation);
  * operational buttons (Export, Copy Regestum, Save).

----

==== Selection of the Document Type ====

The selection of the document type represents a mandatory step in the operational flow.

The user must select an item from the “Select Document Type” dropdown menu before proceeding with the regestum extraction.

The selected type:

  * determines the behavior of the underlying linguistic model;
  * influences the structure of the generated output;
  * constitutes a necessary parameter for starting the analysis process.

In the absence of selection, the system does not allow execution of the “Extract Regestum” command.

----

==== Text insertion ====

The user may manually insert the document text in the “Type a latin text” area.

The text area allows:

  * free typing of content;
  * modification of the text until the extraction step;
  * replacement of the content through the “Reset” command.

The system is primarily designed for the processing of Latin texts, in coherence with the documentary scope of the project.

----

==== Upload via file ====

As an alternative to manual insertion, the user may upload a document through the “Upload a file” button.

The action opens a dedicated modal (“Upload Regesta”) that allows:

  * drag & drop upload;
  * manual file selection from the local device.

Once uploaded, the file content is used as input for the extraction process.

----

==== Starting the regestum extraction ====

Once the document type has been selected and the text has been inserted (manually or via upload), the user may start the regestum generation process using the “Extract Regestum” button.

The action activates the underlying linguistic model (LLM), which analyzes the provided content and produces a structured output in the right section of the screen.

The system requires:

  * selection of the Document Type;
  * presence of textual content in the input area.

In the absence of these conditions, the command is not executed.

----

==== Document state before extraction (Editable) ====

Before executing the “Extract Regestum” command, the document is in a modifiable state.

At this stage:

  * the user may freely modify the inserted text;
  * it is possible to replace the content;
  * it is possible to perform a complete input reset;
  * the system has not yet generated any structured output.

The “Editable” state persists until extraction is started.

----

==== Document state after extraction (Read-only) ====

After the extraction has been executed, the document enters a non-modifiable state.

At this stage:

  * the input area becomes read-only;
  * the original content can no longer be altered;
  * the structured output becomes available in the right section.

The input lock guarantees consistency between the analyzed text and the generated regestum.

To modify the content, the user must use the “Reset” command and repeat the insertion and extraction process.

----

==== Generated output ====

The “Output” section presents the result of the analysis performed by the linguistic model.

The output is structured into the following fields:

  * Input Accuracy Index  
    A synthetic indicator providing information on the level of coherence and completeness of the analyzed input.

  * Sender  
    The issuing subject of the document.

  * Receiver  
    The recipient of the document.

  * Place of emanation  
    The place where the document was issued.

  * Date of emanation  
    The date when the document was issued.

  * Abstract  
    A descriptive summary of the document content.

  * Regestum  
    A structured regestum automatically generated by the system.  
    
In the current implementation, the section “Regesta in italiano” is present, reporting the formal summary of the document in Italian.

All generated fields are read-only and derive exclusively from the processing of the input text.

----

==== Operations available on the output ====

Once the regestum has been generated, the user may perform several operations depending on the level of access.

Reset

Allows clearing both input and output content, returning the document to a modifiable state.

Export

Allows exporting the generated regestum to the user’s local device.

Copy Regestum

Allows copying the regestum content to the clipboard.

Save (authenticated users only)

Authenticated users may save the regestum within the platform by associating it with a selected Collection.

Saving enables subsequent consultation within the “Collections” page.
