CDS/ISIS is a generalized information storage and retrieval system developed by UNESCO that allows users to design structured non-numerical databases, search and retrieve information, and share data through various methods. It provides database design, editing, searching, and publishing functionality. CDS/ISIS is not a relational database but supports some relational features. Documentation, tools, and language versions are available from UNESCO's website and FTP server. Future development will focus on improving performance, reliability, and cooperation with external partners.
