## Abstract

Project Abstract
Due to recent technological advances, it is possible to image the high-resolution structure of brain volumes at
spatial extents that are much larger than was previously possible. Emerging X-ray microtomography (XRM)
methods allow for the collection of whole mouse brains in a high-throughput paradigm, permitting the
generation of sub-micron three-dimensional image volumes in less than a day without the alignment
challenges or tissue clearing approaches of other methods. Similarly, electron microscopy (EM) efforts now
routinely exceed 100 terabytes in scale and projects are underway to map cubic millimeters of brain regions,
resulting in petabytes of image and annotation data. Both of these methods are widely used throughout the
BRAIN Initiative and the broader neuroscience community, and the instruments required to collect these
datasets are becoming more common and higher throughput resulting in an increased need for data storage
and archival solutions that can accommodate these larger datasets that are being generated at an increasing
pace. Finally, the sample preparation of XRM and EM are compatible with and amenable to co-registration,
and work is underway to pursue multimodal experiments; new instruments are now available with the ability
to perform both XRM and EM data collection from a single sample.
Existing paradigms for data storage and access are often insufficient to accommodate the required storage,
processing, and dissemination needed to fully exploit the generated data. At this scale, traditional analysis
approaches are often ineffective; for example, it is difficult for a human to view all of data collected or
manually annotate more than a small fraction of the volume. Contemporary analysis approaches leveraging
automated methods require robust and efficient access to data, which can be challenging when managing
massive datasets spread across many files. Without a standard data storage mechanism, data access is
cumbersome, storage is expensive and can lack sufficient durability, metadata is unreliable or unavailable and
may not be attributable in useful ways, and file formats and organization are often different across
laboratories, resulting in a high-barrier for collaboration and sharing.
Thus, we propose the Block and Object Storage Service Database (bossDB) to deliver a high-performance,
cost efficient data archive by utilizing a cloud-based tiered storage architecture, where data is seamlessly
migrated between low cost, durable object storage (i.e., S3) and a fast in-memory spatial data store. This
system will be developed through an agile process that will actively fold in community stakeholders for
regular reviews and continuous opportunities for design input, and will provide and support integration of a
robust suite of user-facing tools that are vital to foster community adoption, such as a web-based
management console and visualization tool, a Python SDK for programmatic access, and a client to facilitate...
