Many scientific projects rely on a multitude of different software systems for data storage and data exchange. Keeping data findable and accessible can be challenging, especially if data has to be shared between different sites, working groups and institutes. The open source software LinkAhead provides a powerful framework for managing complex data integrated from heterogeneous data sources.LinkAhead is built in a way that data models can be extended and adapted to future requirements by the researchers at any time. Its extendable crawler framework can be adapted to automatically import data and meta data from different repositories and ELN systems, like elabFTW or PANGAEA. LinkAhead also provides a graphical web-interface, as well as an API for automated queries.
