Using IRMA Web Services to create dynamic web applications

Using IRMA Web Services to create dynamic web applications Proof of Concept achieved! by Melanie Ransmeier and Mike Cox

Presentation overview • Project Inspiration • Making it Happen • Search criteria • Data Set-up • Getting the data - REST • Page Layout • Data Processing & Display • Demo • Future Work & Potential

Inspiration!Air Quality in Parks • Goal is to provide park and network specific air quality information. • Identify location specific air quality impacts • Summarize relevant studies and monitoring • Links to available data sources • Idea! Let’s provide all of the significant references too. • Problem – Don’t want to build or maintain a database to store this information.

IRMA Connections • NRInfo already stores and manages reference information • Most of our key references were already in NatureBib and transitioned to NRInfo • Service oriented architecture allows for access to the databases supporting NRInfo from a public facing web page.

Search Criteria Data Set-up • Provide high quality air references • Park/Network specific • Sort by topic • aerosol • contaminants • deposition • haze • mercury • Establish our own reference set • Tie refs to locations in NRInfo • Formalize key-words and add them to NRInfo records • *ARD_Park-Air-Info_Collection • nitrogen • ozone • sulfur • toxics • visibility

More data considerations • Entering new citations • Check for existing records first! • Modify existing records • Ownership = permission to edit key-words and locations. • Making a reference visible on the web • Ref must be “activated” • and made “public” in NRInfo • Information resource sensitivity must be set to “Non-Sensitive” this needs to be set for all legacy records imported from NatureBib or DataStore.

The Programming Goal Create a simple search page that pulls specific references from NRINFO and output formatted data to a web page

REST • “Representational State Transfer” • Fielding (2000) Rest Constraints: • Client-Server • Stateless • Cache • Uniform Interface • Layered 6. Code On Demand (Optional)

Basically You send a web request (URI) to get formatted data! http://example.com?key={key}

NRINFO REST • NRINFO Reference • Returns a Representation of Data in NRINFO database • Here, it’s a subset of information pertaining to a reference • According to Reference Application Help Manual: http://inp2300fcsmaca1/Reference/Reference/Search?units= {unitcodes}&searchField={searchField}&searchStrings= {searchstrings}&format=xml

Reference Service Parameters • Format – *Required • Unit Code(s) • Search Field • Search String • Start Index • Reference Type • Bounding Area

http://inp2300fcsmaca1/Reference/Reference/Search? format=xml& units=ROMO& searchField=keyword& searchStrings=ARD_Park-Air-Info_Collection;aerosol

ARD Search Page Design Basic Query – Unit + Keyword Formatted, Sorted Results

Park List Bound to XML UnitList.xml … <unit> <name> Rocky … • Bound to xml file • easy to change • reduces web page size • Ideally, eventually will pull from Unit service

results.cfm <cf div url = …> Ajax Panel Process Drop Down Values Form REST URL Request Info from NRINFO Apply XSLT to Sort Results Return Formatted Data Profit

XML HTML <cfxmlvariable="myxsl"> <xsl:stylesheetversion="1.0"xmlns:xsl=http://www.w3.org/1999/XSL/Transformxmlns:irma="http://schemas.datacontract.org/2004/07/NRPC.Reference.External.Service.Composition"> <xsl:templatematch="/"> <html> <body> <xsl:for-each select="irma:ArrayOfReferenceList/irma:ReferenceList"> <xsl:sortdata-type="text"select="irma:DisplayCitation"order="ascending"/> <pclass="hanging-indent"> <xsl:value-of select = "irma:DisplayCitation" /> </p> </xsl:for-each> </body> </html> </xsl:template> </xsl:stylesheet> </cfxml> XSLT

On update of Park or subject, region automatically refreshes

Summary • Actively getting freshest data from NRINFO • Reduce Redundancy • Data Storage • Update

Future Work & Potential • Allow multi-select from drop down lists • Include download files when possible • Update GRI & ARD publications pages to draw from NRINFO • Improve efficiency of publication management • Custom delivery of information on webpages • More user-centric
