Introduction

• The Problems
• Lag Time x Task Time,
• Multimedia
• Ubiquitous Applications
• State of the Art
• Ideal Scenario for our work in
• Workflow Process Automation ? WfMC Standards
• Database and Metadata ? XML Family TEXTML
  Server
• Ubiquitous Applications ? .NET Framework
• Our Work
• Architecture for a Workflow Processs Management
  Framework
• Case Study Portuguese Parliament
• Conclusions
• Future Works

3
The Problems

• Ubiquitous Web Applications
• time-aware, location-aware, device-aware, and
  personalised services
• Multimedia
• Indexing rich documents
• XML-based information retrieve
• Lag Time x Task Time
• the process follows the 90/10 rule
• lt Task Time personal software productivity
• lt Lag Time Workflow Automation Process
• electronic distribution of work
• right information right user right time
• monitoring and scheduling delayed tasks

4
State of the Art

• Workflow Automation Process
• WfMC Workflow Reference Model

5
State of the Art

• XML Technologies
• building XML Schemas
• generating XML files
• formating XSL files
• generating HTML files

6
State of the Art

• TEXTML Server
• 100 XML
• dont touch in the native instance of XML file
• parses XML to build markup-based index
• Its a back end system for
• Store
• Index and
• Search information
• ... in a big number of XML documents

7
State of the Art

• Microsoft .NET Framework
• XML Web Services
• SOAP XML HTML
• SOAP defines a XML format for
• method calls
• passing parameters
• according to definition of
• DTD, XML Schema, BizTalk Schema, etc...
• ASP.NET
• Web Forms
• XML Web Services
• TEXTML COM API

8
State of the Art

• .NET FrameworkArchitecture

9
State of the Art

• ASP.NET Core Concepts

• Web development platform
• New programming model

10
State of the Art

• ASP.NET Core Concepts

• Separate layout and business logic
• Use services provided by the .NET Framework
• Code is compiled the first time a page is
  requested
• State management
• Make use of programming languages
• Cross-language integration
• Update files while the server is running!

11
Our Solution

• Architecture of the Proposal Framework

12
Our Solution

• Data Layer

13
Our Solution

• Logic Layer (business)

• ASP.NET
• Web Forms
• access directly the XML content in the Document
  Base by the TEXTML COM API
• ASPX pages requested by clients
• the compilation is only ever done once per ASPX
  file
• all subsequent requests for the page are
  satisfied by instantiating the class generated
• ... this results in great performance!

14
Our Solution

• Presentation Layer

• ASP.NET
• generate HTML files using XSL files
• for each different device
• Offer funcionality using XML Web Services

Web Services are programmable business logic
components that serve as black boxes to provide
access to funcionality via the Internet using
standard protocols such as HTTP, WAP, etc...
15
Our Solution

• Case Study Portuguese Parliament

16
Conclusion

• we did...
• study Workflow Process Management
• use the WfMC patterns
• build XML Schemas
• generate XML files
• we still are
• formating XSL files
• generating HTML, ASPX files
• implementing XML Web Services

17
Conclusion

• for obtain this key aims
• the study of granularity of XML documents that
  supports the proposal framework
• the capacity of crossed-reference data with other
  files or databases in the system
• the front-ends for ubiquitous applications

18
Conclusion

• next step
• prepare the Framework to effectively integrate
  itself with ubiquitous applications
• future works
• to produce an analyze of the XML Database versus
  Relacional Database
• ... and between XML Web Services and classical
  communication protocols
• to describe the intrinsics aspects to integrate
  heterogeneous systems supported by XML Web
  Services
• to extend the work to the European Parliament

We are looking for partners!!! Whos interested
to join us?

Epilogue
Conclusion

• O saber deve ser como um rio, cujas águas
  doces, grossas, copiosas, transbordem do
  indivíduo, e se espraiem, estancando a sede dos
  outros... Sem um fim social, o saber será a maior
  das futilidades
• (Gilberto Freire, Recife BRASIL, 1899)
• ... Without a social aim, the knowledge will be
  the most important of all futilities.
