MACO is based on DSpace open-source code. It is software created by the Massachusetts Institute of Technology (MIT) and Hewlett-Packard. Since 2021, CSUC is a bronze member of the DuraSpace community that develops the software. Its goal is to lead and innovate in open-source repositories aimed at universities, libraries, research centers, and cultural heritage organizations.

MACO documents are available at OpenAIRE, a technical infrastructure that collects research results from connected data providers. It aims to establish an infrastructure of scholarly communication, open and sustainable, responsible for global management, analysis, and manipulation, and as a link for all the research results.

Catalònica, the aggregator of digital content of Catalunya, indexes the documents available at MACO.

MACO documents can also be found through different search engines and aggregators at international and Spanish level, which facilitate research tasks. These search engines and aggregators that collect MACO's content are: Google Acadèmic, OAIster and RECOLECTA.

Through Altmetric, there are displayed alternative metrics that show the citations received on social media via unique identifiers such as DOI or handle.

Access to the content in MACO is also available through the University Union Catalogue of Catalonia (CCUC).
