ABCD Core Scripts (wxis)

The core functionality of the ABCD software is driven by a set of IsisScripts located in the directory: \htdocs\central\dataentry\wxis

These scripts act as the "API" or "Middleware" between the PHP web interface (Central Module, iAH, OPAC) and the CISIS Database Kernel.

Directory Structure​

The scripts are organized based on the modules they serve. Understanding this hierarchy is crucial for troubleshooting and customization.

Root Directory (/wxis)​

Contains the Core Cataloging scripts and general system utilities.

  • Used by: The "Central" module (Data Entry, Database Administration).
  • Examples: actualizar.xis, fullinv.xis, login.xis.

Sub-directories (Modules)​

ABCD separates business logic for specific subsystems into their own folders to avoid conflicts and maintain cleaner code.

  • /acquisitions: Scripts managing the acquisition workflow (suggestions, purchase orders, bidding).
    • Example: order_create.xis
  • /loans: Scripts for the Circulation module (loans, returns, sanctions, user management).
    • Example: prestamo_disponibilidad.xis
  • /opac: Scripts specifically tuned for the Public Interface (OPAC). These are often read-only or restricted versions of the central scripts.
    • Example: opac/buscar.xis (distinct from the root buscar.xis).
  • /stats: Scripts responsible for generating data tables for the Statistics module.
    • Example: cuadros.xis

Common Architecture​

Most ABCD scripts follow a standard pattern:

  1. Parameter Reception: They use <cgitable> or <field action="cgi"> to read inputs from PHP.
  2. Configuration Loading: They often read cipar.par or specific .def files to locate databases.
  3. Execution: They perform a specific <do task="...">.
  4. Output: They output the result (usually in HTML or raw text) via <display>.
