Abstract
Laboratory data are essential for testing and refining of theories and
models in Earth sciences. Recent developments in data mining techniques
and machine learning have made it feasible to utilize and digest large
amounts of information; yet such data must be initially prepared and
structured in a meaningful way. Recognizing the potential and challenges
of data access, multiple efforts are underway in the development of
digital data repositories (Strabospot, Epos). Currently most information
in experimental Geophysics is not accessible in digital, searchable
form. Such information may include: equipment capabilities and
configurations, original and edited experimental data, laboratory
calibrations as well as information regarding testing protocols and
procedures. The LAPS project aims to design and develop resources to
facilitate data workflow and access. It specifically focuses on the
needs of laboratory researchers, students and managers to prepare data
for use in digital data repositories. As laboratories use a wide variety
of hardware and software solutions to acquire and process data, we focus
our efforts on the development of web based tools that do not require
specific local infrastructure and software. One of the main objectives
of LAPS is to establish a coherent and effective way to describe
equipment and experiments across a variety of testing rigs and devices.
To simplify the workflow we are proposing a combination of selecting
pre-configured equipment and experimental profiles and manual data entry
via web form. A completed test protocol containing all experimental
metadata may then be saved locally (e.g., as JSON file) or (optionally)
to a database. Such test protocols can be re-loaded and modified as
needed. To complete the workflow of a successful test, a link to
original or processed data files may be inserted. The data file layout
can be defined in the experimental profile. Upload to a digital data
repository is optional but by adhering to the proposed Strabo/Epos data
model it will not require additional input. While the web based workflow
will be accessible to all users, we also recognize the need to integrate
the system into specific work flow solutions in rock deformation
laboratories. We therefore provide the framework that simplifies local
data management systems and analytical applications.
