| EMEN2 is an object oriented database and electronic lab notebook. It is designed to store scientific data in a freeform way without limiting the ability to search/mine the results. Unlike a traditional database, where the contents of each record type (table) must be defined by a database administrator and strictly adhered to, each individual record in EMEN2 can have arbitrary additional parameters outside the record definition, and all such parameters remain fully searchable. | Structural and computational biologists frequently work with complex data sets assembled from diverse experimental sources, public resources, and analysis methods. Archiving and mining these data sets with their complicated interrelationships remains a persistent challenge, particularly with “open science” initiatives to make entire workflows, including all raw and intermediate data, available with publications. |

| Records in the database may be arbitrarily linked to each other, much like the web. Any record may link to an arbitrary number of other records of arbitrary type (the record's children). Many other records may link to each record (the record's parents). This permits, for example, a publication to be linked into a publications folder as well as being linked to a specific project; or a microscopy session may be a child of both the biological research project as well as the microscope the data was collected on. | To address these needs, we have developed EMEN2, an object-oriented scientific database and electronic notebook. EMEN2 uses a flexible schema based on plain text descriptions of experimental protocols. Investigators can use standard protocols shared throughout the community, or local protocols used within a single lab group. While originally developed to serve the needs of the cryo-EM community, we believe EMEN2’s architecture provides an excellent foundation for many other scientific endeavors. |

EMEN2
An extesible, object-oriented electronic lab notebook
Structural and computational biologists frequently work with complex data sets assembled from diverse experimental sources, public resources, and analysis methods. Archiving and mining these data sets with their complicated interrelationships remains a persistent challenge, particularly with “open science” initiatives to make entire workflows, including all raw and intermediate data, available with publications.
To address these needs, we have developed EMEN2, an object-oriented scientific database and electronic notebook. EMEN2 uses a flexible schema based on plain text descriptions of experimental protocols. Investigators can use standard protocols shared throughout the community, or local protocols used within a single lab group. While originally developed to serve the needs of the cryo-EM community, we believe EMEN2’s architecture provides an excellent foundation for many other scientific endeavors.
