Introduction

Creative intent in project lifecycle

Three steps towards sustainable intent expression

Blender perspective

XRCE, Document Structure

Nothing like Blender : documents, document collections, Web pages

Research directions

The Document as a trace of social relations reconstructed by computer systems*

Document understanding and processing • Methods and technologies to analyse document collections and

compute information relevant to domain-specific contexts of use

Document network understanding• Methods and technologies to discover interactions, patterns and

trends involving actors and communities. within large collections of inter-linked documents

Qualification• Methods and technologies to qualify XML resources in

distributed/collective ecosystems

Towards expressing the creative intent beyond processes and projects

The value of sustainable intent expression grows as agility becomes critical For project efficiency

For organizations • Asset management (competence, knowledge and processes)

• Interactions with external bodies, partnerships



STEP 0: Traditional IT development outcome Preserve digital objects produced at a given point in time

Hard to keep up and running or reuse because of technology evolution (hw/sw)

Hard to interpret• formats and codes,

• implicit knowledge,

• unmotivated or untraceable decisions,

• evolving and lost semantics,

• lost skills

Struggle to reuse, revive, migrate, emulate, reproduce








• lost skills


STEP 1: Abstract development through modeled design








• lost skills



STEP 2: Intent expression through project task management


Model-based design Symbolic description of objects, irrespective of their specific implementation

Customized for specific domains, enabling domain-relevant concept descriptions

Well adapted to SOA Efficiency,

Task distribution,

Readability

Provides some basic expression of intent through abstraction Less dependency on computing infrastructure/implementation

Abstract development through modeled design: our experience

XeProc, a model for a very focused domain: document understanding through XML processing

XeProc designer to create domain objects XML pipes, doc processing with features and relations

… as Blender enables one to create meshes with their attributes





The XeProc designer• provides means to graphically manipulate abstract

representations of objects relevant to the application domain

• provides immediate design feedback

– interpretation (player/builder) over reference collections

– validation

– visual error feedback

• Generated through EMF/GMF in Eclipse

At this stage, one preserves the designer results but not the design process

STEP 2: Intent expression through project task management

Intent is reflected by interactions between actors across their different roles

Proposed approach: Traditional task management as a means to track interactions Interactions captured through selected tasks

Tasks are instances of an agreed task model• Objectives

• Requirements

• Project development

• Q/A

Task descriptions anchored to objects under development Anchoring makes tasks interpretation more explicit

… and facilitates project navigation in task context

Task instantiated as annotations of objects under development A natural medium for content creators and designers

Annotations must support anchoring compatibility with all viewpoints of the project lifecycle

TASK MODELING SPACE

MDA from the task model

Task models are created via a task model editor

Modeling is based on a DSL dedicated to tasks and relations

Task model

Task model, reference viewpoints and mappings

Domain objects are described by a sustainable reference viewpoint• Using an Object Description Language (XML) and an anchoring language (à la XPath)

The task model links to the reference viewpoint : Anchoring methods are associated to tasks as behaviors

Backup

Digital preservation

High risk but still little awareness outside focused sectors (libraries, archives, e-science)

The 1086 Domesday Book, instigated by William the Conqueror, is still intact and available to be read by qualified researchers in the Public Record Office. In 1986 the BBC created a new Domesday Book about the state of the nation, costing £2.5 million. It is now unreadable. It contained 25,000 maps, 50,000 pictures, 60 minutes of footage, and millions of words

Analogy between the document and 3D worlds

Design domain vs. target usage (visualise, read, play)

Internal structure (source, XML , Bender) vs. external representations (PDFs, 3D scenes)

Technical (designers) vs. content producers (creators, annotators)

source data vs. intent and semantics

Project dev (support requests) vs. persistent intent

Interaction between the two domains: tests involving both communities

The document / 3D parallel

Design (source) Target usage

Doc structure Visu, read docs

Blender struct. Play 3D

Designers, technical content creators,

Support dev., support requests Persistent intent

TESTS

The XeProc metamodelThe XeProc metamodel is described by a UML class diagram

XeProc models specify logical XML document processing pipelines

Human annotation Automated annotation

1) Research:- Provides document processing through DSL

2) Additional requirements from customer: semantic annotation- Human interface for manual annotation- Automated semantic annotation of XML documents

- Design the semantic model with the customer

- Augment XML processing with semantic models - Generate the annotation interface
