Later to analysis phase and software test was determined that be used Heritrix software, applied in most capture of digital resources projects. This is a software charge to compile web pages as the user sees when surf the Internet and store it in compressed files with ARC extension. Then, Heritrix software is complemented by NutchWax, or by combination with Hadoop and Wayback, doing an indexing process to compiled information that will permit use these index for localize collection resources from query interfaces: Wera, that permits search from keywords through generated indexes by NutchWax; and Wayback, that lets consult by URL in generated indexes by Hadoop and same Wayback.
Has been used Web Curator Tool software, developed by National Library of New Zealand and British Library, as a document management system that permits allocate metadata to a significant part of collection, in order to integrate, in future, funds of deposit to search in other catalogs, from the Biblioteca de Catalunya or other institutions.
