Challenges There was little success in attracting dues-based members. There was some interest in using the BRIDGE ID and its associated data as an open data resource, by not for pay. Beyond the original partners, we found few organizations and companies that wanted to use the BRIDGE ID for data interoperability to keep databases synchronized and current. It was hard to penetrate the market for unique organizational identifiers among established and well-funded vendors such as LEI, DUNNS, and a large number of country-based identification systems world-wide. The level of manual effort necessary to curate and deduplicate country-based organizational data internationally far exceed our funding expectations and challenged our sustainability.
