(More) Transparency Transformation

transparency transformation solution architecture tools and techniques george thomas #gtra-sym09

agenda
An overview of Web Oriented Architecture (WOA) design principles that have made the Web the most successful distributed computing platform ever created will be given.
Technologies for exposing raw data and publishing semantically enriched structured data for persistence and syndication on the Web as public records will be described.
Technologies that enable interoperability across these published assets and currently disparate data sources to achieve low cost, large scale data federation will be described.
Widgets and services that consume and transform this data for interactive and integration purposes will be discussed in the context of different stakeholder views.
A Web-scale approach to Business Intelligence leveraging Cloud Computing approaches to data archive analysis will be described.
Finally, the applicability of the proposed solution architecture to the Federal Segment Architecture Methodology and tools like Visualization to Understand Expenditures in IT will be discussed.

Web Oriented Architecture (WOA)
REpresentational State Transfer (REST)
The architectural style of the World Wide Web
aka Resource Oriented Architecture (ROA)
hyperlinks dereference (information) resource representations
HTTP URI's and content negotiation
user agent prefers .htm, .xml, .rdf, .etc
statefulness
servers maintain resource state, clients maintain application state
RESTful Web services
HTTP uniform interface
CRUD analog to HTTP PUT/GET/POST/DELETE
contrast to Remote Procedure Call (RPC) style Web services
SOAP/WSDL, you design the methods to invoke
global visibility (the Web) and persistence (permalinks)
caching, crawling, indexing

agenda

XForms - human data capture
Orbeon server side XForms engine, Ajax browser GUI's
catalog and builder apps
create new XSD bound forms
populate, persist, search
Tomcat and eXist
off-line capability
transformation pipeline

Atom Publishing Protocol (APP)
automated invocation of the RESTful Web service
HTTP PUT/POST the spreadsheet or XML instance doc
to atomserver.codehaus.org
where else is APP used?
Google Data API's, Microsoft Live Framework

Atom Syndication Format
transform XForm or APP captured info into XHTML+RDFa
(permalinked) public recordset in feed entry <content>

RDFa enabled 'deep link' discovery
Rich Snippets from Google
SearchMonkey from Yahoo

the london-gazette.co.uk

london-gazette.co.uk/listing

web page = web service

agenda

Web as DB - Web API
Linked Open (Government) Data (LOD)
SPARQL endpoints
linkeddata.org

linkedmdb.org – LOD example

RDF/XML from W3C Tabulator

from web of docs to web of data

querying the Web

faceted browsing
click through on this (S-P-O) result set, use as query

federated correlation
graph based dynamic schema evolution across silos
centralization/normalization not required (or realistic/practical!)

agenda

many to many set visualization

ad-hoc analyst/end-user 'meshups'

agenda

analytics in the wild

cloud scale analytics
Google
GFS and MapReduce
Proprietary
page rank impl
Apache Hadoop
HDFS and MapReduce
open source
Amazon EMR, Cloudera
facebook.com

agenda

application to EA discipline
getting there from here
stop:
publishing / analyzing / visualizing unstructured data
using structure data only in file or message exchanges
start:
align Gov and Web architecture (including EA KB's!)
divide and conquer / publish component ontologies
linking them
continue:
embracing emergent structure and continuous improvement
using open source and enabling crowd-sourcing
