Module-Specific Scripts

While the root scripts handle general cataloging, the specialized modules of ABCD have their own dedicated IsisScripts located in subdirectories.

1. OPAC Scripts (`/wxis/opac`)

The OPAC (Online Public Access Catalog) scripts are designed for high performance and security, as they are exposed to the public web.

opac/buscar.xis:
- Function: Executes searches in the OPAC.
- Difference from Root: Unlike the Central buscar.xis, this script often handles facets, integrates with the meta-search engine, and strictly respects the opac_conf.def visibility rules (hiding private fields).
opac/status.xis:
- Function: Checks the status of a record (copies availability) without retrieving the full bibliographic data.
opac/reserve_check.xis & opac/reserve_update.xis:
- Function: Manages the reservation process by authenticated users directly from the web interface.

These scripts interact primarily with the Users (users) and Transactions (trans) databases, linking them to the bibliographic databases.

loans/prestamo_disponibilidad.xis:
- Function: Checks if a specific copy of a book is available for loan based on policies (user category vs. item object category).
- Logic: It reads the "Policy" database (politica) and compares dates and counts.
loans/leer.xis:
- Function: Reads user data or transaction details. It is specialized to handle the specific fields of the loan system (User ID, Object ID, Dates).

Scripts handling the administrative workflow of purchasing library materials.

acquisitions/order_create.xis:
- Function: Generates a new purchase order.
- Operations: Creates records in the Acquisitions database (acq), linking them to providers and budget lines.

stats/cuadros.xis:
- Function: Generates the raw data matrices for statistical tables.
- Technique: heavily uses <do task="list"> with type="freq" (Frequency Lists) to count occurrences of fields (e.g., "Authors per Year", "Loans per User Category").
