The cataloguing experience presented addresses two key challenges of cataloguing industrial heritage assets. On the one hand, despite their value and interest, some of these assets are little known and difficult to identify. Moreover, on the other hand, this heritage typology needs further promotion and valuation. In this context, collaborative cataloging responds to both challenges from its initial approach. Unlike cataloging tasks developed by small teams, involving many people throughout the territory allows to take advantage of the local knowledge of each participant. However, in addition, each participant contributes to the dissemination of the goods collected in the generated catalog. First in a passive way, when knowing the contributions of the rest of the participants. Secondly, actively, by disseminating the cataloging initiative developed among their contacts. This cataloguing experience has been developed with the students of the subject Environmental Project Management during the last four courses. The assets selected by the students (106) as case studies to develop a reuse project are shown in an open web map, which includes the narrated video presentation of the proposal developed for some of them (25). The obtained results contribute both the identification and promoting of this kind of assets.
