Introduction

• UniProt Databases

Primary data source for GridEnablement of PIR
6
Project Overview

• Project Goal Provide the most comprehensive and
  fully annotated protein related information for
  genomic and proteomic cancer research
• Major Functionality Providing methods to query
  and retrieve protein related information for the
  cancer research community
• Being developed in two phases
• First phase Jan 1 Aug 1 2005
• Demonstrate PIR data source can be discovered and
  consumed in caBIG
• Make PIR data source caBIG silvercomplaint
• Originally final product was web services
• June 13 2005 the project changed direction to
  become a grid service

7
Data Model

• Current Total 48 objects 51 attributes

8
Data Model

• Protein/Gene related objects

9
Data Model

• Annotation related objects Protein Features

10
Data Model

• Taxonomy related objects Proposed as Taxonomy
  CDE

11
Project Architecture
Client
Data Access Objects/PIR Data Service
Object to Relational Mapping
Domain Objects
UniProtKB Database
12
Process to Silver Compliance

• Month 1 Use cases developed with adopter from
  UPenn
• Setting Search Criteria
• Simple Search based on individual field
  UniProtKB PIR ID or accession number NCBI
  Taxonomy ID Protein name etc.
• Advanced Search based on two fields combined with
  Boolean operators AND OR and AND_NOT
• AllID Search a Googlelike search for the
  identifier fields if source of identifier is not
  known
• Batch Retrieval using multiple UniProtKB IDs or
  accessions
• Setting Response Criteria
• UniProtKB XML or FASTA
• Month 2 Test approach document approved
• Month 34 Requirements and specifications
  document approved
• Month 4 Database schema developed reverse
  engineered

13
Process to Silver Compliance

• Month 4.5 First version of the object model and
  semantic annotation report UniProtKB
  recordbased Object Model 70 objects 130
  attributes

14
Process to Silver Compliance

• Month 5 First version of the web services
  developed and tested
• Month 5.5 June 13 Feedback from caCORE team on
  the first version of the object model
• Design a protein domain model rather than a
  UniProtKB recordbased model
• Use caCORE SDK to generate the middle layer
• New page in Gridenablement of PIR project web
  services development became unnecessary for grid
  deployment put more emphasis on object modeling

15
Process to Silver Compliance

• June 17 Second version of the object model
  submitted for VCDE/caCORE Workspace review

16
Process to Silver Compliance

• June 22 Review object model with VCDE and caCORE
  teams
• Use bidirectional associations unless necessary
• Use java.util.Collection rather than list
• Follow caCORE SDK naming conventions
• Replace complex data types i.e. Lists with
  association classes
• Implement subclass of Feature to express
  semantics
• June 24 Third version of the object model is
  submitted for VCDE/caCORE Workspace review
• June 28 Semantic annotations for the first
  version of the object model received from VCDE
  team

17
Process to Silver Compliance

• June 30 Object model finalized

18
Process to Silver Compliance

• July 2 Semantic annotation partially done
  using the annotations of the first object model
• July 11 Code generated using caCORE SDK 1.0.2
  ORM completed first version of silver level
  application deployed
• July 21 Semantic annotation completed 149
  Concepts

19
Process to Silver Compliance

  generated API
• July 25 Migration to caCORE SDK 1.0.3

  ORM modified current version of silver level
  application deployed
• August 5 Gridnode deployed for caCORE SDK 1.0.3
  generated API

  production server

20
Functionality Exposed to the Grid

• GridEnablement of PIR project is a data service
• All the objects in our model exposed to the grid
• Example queries
• Find the proteins for the gene BRCA2 Breast
  Cancer Gene 2
• Find all the proteins that contain the domain
  BRCA2 repeat PFAMPF00634 a domain in Breast
  cancer type 2 susceptibility protein
• ID mapping Find all the database
  crossreferences from various databases
  corresponding to RefSeq Accession NP_009225
• Since all the PIR and UniProt databases are
  public no security layers implemented

21
Process of Grid Enablement

• Download prerequisites CVSGrab Ant JDK
  1.4.2_04
• Set environment variables JAVA_HOME ANT_HOME
  CVSGRAB_HOME
• Run ant script bootstrap.xml provided by caGRID
  team
• Set more environment variables CATALINA_HOME
  OGSADAI_LOCATION GLOBUS_LOCATION
• Copy the client.jar generated by caCORE SDK to
  the correct data services directory
• Change the configuration so that it points to
  HTTP server URL for your data service
• Deploy the service with ant f bootstrap.xml
  deployDS
• Start Tomcat Server

Lessons Learned / Technical Difficulties

• Before starting
• Read caCORE SDK Programmers Guide especially
  Chapter 5 Generating UML Models
• Download and install caCORE SDK
• Keep in mind caGRID and caCORE SDK under
  development
• Use case development
• Identify caCORE SDK limitations

31
Lessons Learned / Technical Difficulties

• Object modeling most important step
• Considerations
• Scientific meaning if possible Dont do record
  modeling
• Use cases Consider search criteria objects
• caCORE SDK constraints Consider naming
  conventions id attribute constraints
  supported collection types. e.g. List is not
  supported
• Data related constraints Include only
  associations or objects based on your data. e.g.
  Gene to Protein but not Protein to DNASequence
• Semantics Express semantics and avoid using
  type attributes. e.g. ProteinFeature subclasses
  Lineage
• Ask for a VCDE representative before you begin
  employ an iterative approach

32
Lessons Learned / Technical Difficulties

• Semantic annotation/caDSR load
• Enter tagged values while modeling
• Review semantic annotation report to check
  classifications of Concepts ObjectClass
  ObjectClassQualifier Property
  PropertyQualifier
• Ensure all the Concepts are included in
  Annotated Model before you send to caDSR
• Code generation / Grid deployment
• Using caCORE SDK helped in gridenabling PIR

33
Lessons Learned / Technical Difficulties

• Database Performance
• In caCORE SDK generated SQL statements all
  string fields are lowercased additional
  functionbased indexes are needed
• select from. where lowerPRIMARYACCESSION
  p88888
• Objecttorelational mapping
• New id attribute constraint introduced in
  caCORE SDK 1.0.3
• Option 1 Change the database schema add id of
  type Integer to all the tables caBIO
• Option 2 Map existing primary keys as id so
  id can be String or Integer PIR

34
Wish List

• Semantic annotation
• Excel spreadsheets are errorprone a tool that
  will make semantic annotation easier
• Traversing the object model
• Checking errors wrong classifications missing
  annotations etc.
• caCORE SDK
• Googlelike/any field search
• Allow optional exact string search
• Use of logger instead of System.out. or
  System.err.
• Support queries involving class inheritance
• Support Boolean queries involving multiple
  collection type attributes
• caGRID
• Training opportunities for developers
• Documentation
