Modern science increasingly involves managing and processing large amounts of distributed data accessed by global teams of researchers. To do this, we need systems that combine data, meta-data and workflows into a single system. This paper discusses such a system, built from a number of existing technologies. We demonstrate the effectiveness on a case study that analyses MRI data.

UML object diagrams for the (A) DICOM, (B) XCEDE, (C) PSS and (D) CCLRC object models. In addition to the UML notation the horizontal arrows indicate equivalence of objects between the different models. The UML notation can be summarized as follows: Objects (or classes) are shown in rectangles and named relationships are shown between objects that are qualified by their cardinality (* means infinity, 0..* means 0 to infinity). The relationship direction is indicated via an arrow. Filled diamonds indicate that the relationship is containment (also called composition) and open diamonds indicate an aggregation (has) relationship.
UML object diagram of the Framework object model (see Table 1 for definitions). (A) When subjects are not re-used across multiple projects, only the project specific objects are used. (B) If subjects participate in multiple projects then additional objects are required. (C) The Method object contains Steps, each of which is comprised of a possible State Change, production of a DataSet and a Branch Point.
The metadata specified by a particular Method (developed for a particular Project) that is required to create a Subject. The adaptive graphical interface interrogates the Method to discover the required metadata. Metadata are presented in XML fragments. Some metadata are predefined and immutable (e.g. species) whereas other metadata requires entry.
The adaptive interface shows the object trees for the projects that the user is authorized to access. The Project with citable ID 1005.4.361 is opened and the ExMethod object 1005.4.361.1.1 is displayed. For presentation, this figure shows a simplified version of the ExMethod object (it has more steps in reality). The inset shows the (immutable) metadata for the Perfusion step. It can be seen that the overall Method (1005.5.388), from which this ExMethod is instantiated, was built from a number of Method fragments (1005.5.[384,385,386]).

A framework that integrates an object model, research methods (workflows), the capture of experimental data sets and the provenance of those data sets for subject-centric research is presented. The design of the Framework object model draws on and extends pre-existing object models in the public domain. In particular the Framework tracks the state and life cycle of a subject during an experimental method, provides for reusable subjects, primary, derived and recursive data sets of arbitrary content types, and defines a user-friendly and practical scheme for citably identifying information in a distributed environment. The Framework is currently used to manage neuroscience Magnetic Resonance and microscopy imaging data sets in both clinical and basic neuroscience research environments. The Framework facilitates multi-disciplinary and collaborative subject-based research, and extends earlier object models used in the research imaging domain. Whilst the Framework has been explicitly validated for neuroimaging research applications, it has broader application to other fields of subject-centric research.

... Scientific workflows allow domain scientists to focus on their science, leaving the configuration and optimization of the computational infrastructure to other computing professionals. This approach is being recognized as valuable for scientists to access and analyze data [18]. ...

Integration of modern data management practice with scientific workflows

... The need for raw data collection and management, as well the accurate recording of data provenance of processed data, for large biomedical imaging research studies, has resulted in the recent development of software packages, unlike clinical picture archiving and communication systems (PACS), that are designed specifically for research studies [16][17][18][19]. Along with the collection and storage of the primary data, these systems have been designed to store processed data as well as provenance information regarding the processing steps [20], although tight integration of the provenance information within the informatics platform is still under active research and development. ...
