-= A Metadata Model for Facilities Science =
-
-The model is organised around a notion of Studies, a study being a body of
scientific work on a particular subject of investigation. During a study,
a scientist would perform a number of investigations e.g. experiments,
observations, measurements and simulations. Results from these
investigations usually run through different stages: raw data, analysed or
derived data and end results suitable for publication. The model has a
hierarchical model of the structure of scientific research programmes,
projects and studies, and also a generic model of the organisation of data
sets into collections and files.
-
-For specific data sets the model provides links to the files holding the
actual data. Users can then use these links to access the data with their
own applications for analysis as required. Data should be grouped
accordingly, and associated with the appropriate experimental parameters.
Not all information captured in specific metadata schemas would be used to
search for this data or distinguish one data set from another, give
possibility to select special parameter.
-
- * *Investigation*: forms the fundamental unit of the model, with a
title, abstract, dates, and unique identifiers referencing the particular
study. Also associated with the investigation are the facility and
instrument used to collect data.
- * *Investigator*: describes the people involved in the study, together
with their institution and role in the study (e.g. principle investigator,
research student).
- * *Topic and Keyword*: provide controlled and uncontrolled vocabulary to
annotate and index the investigation.
- * *Publication*: provides links to publications associated with
(motivating or derived from) the investigation.
- * *Sample*: information on the material sample under investigation
within the study. The model has fields for a sample’s name, chemical
formula and any associated special information about it, such as specific
safety information on a toxic material.
- * *Dataset*: one or more datasets can be associated with an
investigation, representing different runs or analyses on the sample.
Initially a raw data set can be attached to the investigation, but
subsequently, analysed datasets can also be associated.
- * *Datafile*: the CSMD takes a hierarchical view of data holdings, as
data sets may contain other dataset as well as units of storage, typically
datafiles. Each datafile has more detailed information, including its
name, version, location, data format, creation and modification time, and
fixity information such as a Checksum.
- * *Parameter*: parameters describe physical entities associated with the
investigation, such as temperature, pressure, or scattering angle,
describing either the parameters of the sample, the environment the data
was collected in, or the parameters being measured. Thus parameters are
associated with the sample, dataset or the datafile, and have names, units,
values, and allowable data ranges.
- * *Authorisation*: the CSMD can associate conditions on investigations
and data sets, so that user specified access conditions can be specified.
Thus the authorisation entity can record which user in which role can
access data on specific investigations.
