What is the state-of-the-art today
Most other vendors still trying to build ADCycleRequires all tools to integrate around centralized repository
ndash Data import (duplication) for foreign toolsWorks as well as other centrally-planned economies have worked
ndash Do your companyrsquos needs match a fixed pre-planned solution or is an open integrated economy a better model

What is Linked Data
1 Use URIs as names for things 2 Use HTTP URIs so that people can look up those names 3 When someone looks up a URI provide useful information using the
standards (RDF SPARQL) 4 Include links to other URIs so that they can discover more things
Isnrsquot this just REST

Linked Data ndash a major transformation
There have only been two major model shifts in my 30+ year career
ndash First was shift to client server from mainframe This is the second
Adopting this simple model turns everything on its head ndash The HTTP resources are central your application a minor detailndash The HTTP URLs are permanent reality the data in the database a detailndash Closed fixed in scope -gt open extensible scopendash Fixed in time -gt everything evolves over timendash Donrsquot import data ndash address it where it is

What is RDF
A ldquouniversalrdquo data representation for the webndash Relational IMS COBOL XML object hellip data can all be expressed in RDF
A very simple model and syntax for representing data on the world wide webndash RDF is like property value pairsndash RDF adds ldquosubjectrdquo ndash what is it the property of ndash so triples not pairsndash RDF properties are themselves resources with URLs
Thatrsquos about it ndash most of the rest is hype and pretention or detailndash RDF also can describe containers and collectionsndash RDF has the notion of type but itrsquos not similar to OO type itrsquos like type in the natural worldndash There is a language for querying over RDF called SPARQL (SPARQL adds graphs so quadruples not
triples)ndash You can write down RDF data in XML as a twisted experiment of no value but there are much nicer
more natural formats

OSLC Core Spec
Applies to all resources in an OSLC system Tries to answer some simple questions on how to use linked data
ndash What URLs can I POST to create new resourcesbull What properties couldshould I set when POSTing to these URLs
ndash How do I query the resources already POSTed at an URLbull What properties might be available to query on a set of resources
ndash How is pagination of large representations handledndash How can I delegate to the UI of another service instead of dealing with its datandash Best practices for expressing hyper-links between resources (eg link properties)ndash Partial Update (there is a reason that SQL has no equivalent of PUT only PATCH)
A bit like a superset of APP except hellipndash Linked data compatiblendash Generic - doesnrsquot require you to model your domain as a blog (feed entry)ndash Simpler Solves more problems

bull Need to agree on some domain-specific termsndash Donrsquot try to define all the properties of a resource like defect
bull Every teamorganization wants different ones
ndash Focus on those properties that are important for integration scenariosbull Eg Is a defect closedbull Eg What requirement does this test-case test

Does the application own storage
Typical Application modelndash Data access is through an application application controls integrityndash Storage is an application concern totally private and fixed
Traditional IDE modelndash Data in files multiple tools work on the files files may be all screwed upndash Permanent Storage (eg SCM versioning) is a peer application - file
system is just a temporary shared cache between applications andpermanent storage

Linked Data Challenges - detail
Think of ldquodata policy that changes with timerdquo not ldquoinherent characteristicsrdquo
bull Eg Defects must have a priority between 1 and 3 ndash changeable policy
Assume applications are ldquoblack boxesrdquo ndash use protocols not frameworks to integrate (cf Eclipse)

Fat client or resource-oriented UI
You can write fat clients in the browser toondash That is exactly what most experienced programmers will do
Fat clients have good support for specific workflowsFat clients have problems
ndash Long load timesndash Closed systems (what do you do when a link leads to pdf or html or other)ndash More difficult to evolve when workflows change
Another option is ldquopage per resourcerdquo UIsndash Embrace page switches

OSLC Core Spec
Applies to all resources in an OSLC system Tries to answer some simple questions on how to use linked data
ndash What URLs can I POST to create new resourcesbull What properties couldshould I set when POSTing to these URLs
ndash How do I query the resources already POSTed at an URLbull What properties might be available to query on a set of resources
ndash How is pagination of large representations handledndash How can I delegate to the UI of another service instead of dealing with its datandash Best practices for expressing hyper-links between resources (eg link properties)ndash Partial Update (there is a reason that SQL has no equivalent of PUT only PATCH)
A bit like a superset of APP except hellipndash Linked data compatiblendash Generic - doesnrsquot require you to model your domain as a blog (feed entry)ndash Simpler Solves more problems

What is RDF
A ldquouniversalrdquo data representation for the webndash Relational IMS COBOL XML object hellip data can all be expressed in RDF
A very simple model and syntax for representing data on the world wide webndash RDF is like property value pairsndash RDF adds ldquosubjectrdquo ndash what is it the property of ndash so triples not pairsndash RDF properties are themselves resources with URLs
Thatrsquos about it ndash most of the rest is hype and pretention or detailndash RDF also can describe containers and collectionsndash RDF has the notion of type but itrsquos not similar to OO type itrsquos like type in the natural worldndash There is a language for querying over RDF called SPARQL (SPARQL adds graphs so quadruples not
triples)ndash You can write down RDF data in XML as a twisted experiment of no value but there are much nicer
more natural formats
