EHR requirements
Published requirements for the EHR are principally available via ISO 18308. They are statements defining the generic features necessary in any Electronic Health Record for it to be communicable and complete, retain integrity across systems, countries and time, and be a useful and effective ethico-legal record of care. Examples of requirements are provided in four themes: -EHR functional requirements; Ethical, legal, and security requirements; Clinical requirements; Technical requirements. The main logical building blocks of an EHR are described using the terminology of CEN TC251 ENV13606. Examples are given of the placement of attributes to satisfy contextual and other requirements at the level of specific building blocks. A worked example of the use of the building blocks is given for the request-report cycle for an imaging investigation
Generic service integration in adaptive learning experiences using IMS learning design
IMS Learning Design is a specification to capture the orchestration taking place in a learning scenario. This paper presents an extension called Generic Service Integration. This paradigm allows a bidirectional communication between the course engine in charge of the orchestration and conventional Web 2.0 tools. This communication allows the engine to configure external services so as to adjust their behaviour, and also retrieve information about their activity and use it to influence the orchestration process. This extension impacts all the phases of the life cycle of a learning activity: authoring, deployment and enactment. The paper analyses this impact and proposes appropriate adjustments. A pilot test was conducted and the obtained results show that learning experiences that adapt their flow-based on third party tools while maintaining interoperability, reusability and self-containment requirements are feasible.Work partially funded by the Learn3 project, “Plan Nacional de I+D+I” TIN2008-05163/TSI, the Best Practice Network ICOPER (Grant No. ECP-2007-EDU-417007), the Flexo Project “Plan Nacional de Investigacin Cientfica, Desarrollo e Innovación Tecnológica” (Ref.

Model-Driven Development of Interactive Multimedia Applications
The development of highly interactive multimedia applications is still a challenging and complex task. In addition to the application logic, multimedia applications typically provide a sophisticated user interface with integrated media objects. As a consequence, the development process involves different experts for software design, user interface design, and media design. There is still a lack of concepts for a systematic development which integrates these aspects.
This thesis provides a model-driven development approach addressing this problem. Therefore it introduces the Multimedia Modeling Language (MML), a visual modeling language supporting a design phase in multimedia application development. The language is oriented on well-established software engineering concepts, like UML 2, and integrates concepts from the areas of multimedia development and model-based user interface development.
MML allows the generation of code skeletons from the models. Thereby, the core idea is to generate code skeletons which can be directly processed in multimedia authoring tools. In this way, the strengths of both are combined: Authoring tools are used to perform the creative development tasks while models are used to design the overall application structure and to enable a well-coordinated development process. This is demonstrated using the professional authoring tool Adobe Flash.
MML is supported by modeling and code generation tools which have been used to validate the approach over several years in various student projects and teaching courses. Additional prototypes have been developed to demonstrate, e.g., the ability to generate code for different target platforms. Finally, it is discussed how models can contribute in general to a better integration of well-structured software development and creative visual design
A knowledge-based system design/information tool
The objective of this effort was to develop a Knowledge Capture System (KCS) for the Integrated Test Facility (ITF) at the Dryden Flight Research Facility (DFRF). The DFRF is a NASA Ames Research Center (ARC) facility. This system was used to capture the design and implementation information for NASA's high angle-of-attack research vehicle (HARV), a modified F/A-18A. In particular, the KCS was used to capture specific characteristics of the design of the HARV fly-by-wire (FBW) flight control system (FCS). The KCS utilizes artificial intelligence (AI) knowledge-based system (KBS) technology. The KCS enables the user to capture the following characteristics of automated systems: the system design; the hardware (H/W) design and implementation; the software (S/W) design and implementation; and the utilities (electrical and hydraulic) design and implementation. A generic version of the KCS was developed which can be used to capture the design information for any automated system. The deliverable items for this project consist of the prototype generic KCS and an application, which captures selected design characteristics of the HARV FCS
London SynEx Demonstrator Site: Impact Assessment Report
The key ingredients of the SynEx-UCL software components are:
1. A comprehensive and federated electronic healthcare record that can be used to
reference or to store all of the necessary healthcare information acquired from a
diverse range of clinical databases and patient-held devices.
2. A directory service component to provide a core persons demographic database to
search for and authenticate staff users of the system and to anchor patient
identification and connection to their federated healthcare record.
3. A clinical record schema management tool (Object Dictionary Client) that enables
clinicians or engineers to define and export the data sets mapping to individual
feeder systems.
4. An expansible set of clinical management algorithms that provide prompts to the
patient or clinician to assist in the management of patient care.
CHIME has built up over a decade of experience within Europe on the requirements
and information models that are needed to underpin comprehensive multiprofessional
electronic healthcare records. The resulting architecture models have
influenced new European standards in this area, and CHIME has designed and built
prototype EHCR components based on these models. The demonstrator systems
described here utilise a directory service and object-oriented engineering approach,
and support the secure, mobile and distributed access to federated healthcare
records via web-based services.
The design and implementation of these software components has been founded on
a thorough analysis of the clinical, technical and ethico-legal requirements for
comprehensive EHCR systems, published through previous project deliverables and
in future planned papers.
The clinical demonstrator site described in this report has provided the solid basis
from which to establish "proof of concept" verification of the design approach, and a
valuable opportunity to install, test and evaluate the results of the component
engineering undertaken during the EC funded project. Inevitably, a number of
practical implementation and deployment obstacles have been overcome through
this journey, each of those having contributed to the time taken to deliver the
components but also to the richness of the end products.
UCL is fortunate that the Whittington Hospital, and the department of cardiovascular
medicine in particular, is committed to a long-term vision built around this work. That
vision, outlined within this report, is shared by the Camden and Islington Health
Authority and by many other purchaser and provider organisations in the area, and
by a number of industrial parties. They are collectively determined to support the
Demonstrator Site as an ongoing project well beyond the life of the EC SynEx
Project.
This report, although a final report as far as the EC project is concerned, is really a
description of the first phase in establishing a centre of healthcare excellence. New
EC Fifth Framework project funding has already been approved to enable new and
innovative technology solutions to be added to the work already established in north

Toward a Scalable Census of Dashboard Designs in the Wild: A Case Study with Tableau Public
Dashboards remain ubiquitous artifacts for presenting or reasoning with data
across different domains. Yet, there has been little work that provides a
quantifiable, systematic, and descriptive overview of dashboard designs at
scale. We propose a schematic representation of dashboard designs as node-link
graphs to better understand their spatial and interactive structures. We apply
our approach to a dataset of 25,620 dashboards curated from Tableau Public to
provide a descriptive overview of the core building blocks of dashboards in the
wild and derive common dashboard design patterns. To guide future research, we
make our dashboard corpus publicly available and discuss its application toward
the development of dashboard design tools.Comment: *J. Purich and A. Srinivasan contributed equally to the wor
Script-Based QOS Specifications for Multimedia Presentations
Multimedia presentations can convey information not only by the sequence of events but by their timing. The correctness of such presentations thus depends on the timing of events as well as their sequence and content. This paper introduces a formal specification language for playback of real-time presentations. The main contribution of this language is a quality of service (QOS) specification that relaxes resolution and synchronization requirements for playback. Our definitions give a precise meaning to the correctness of a presentation. This specification language will form the basis for a QOS interface for reservation of operating system resources
