Using IRMA Web Services to create dynamic web applications

Proof of Concept achieved!

Inspiration!Air Quality in ParksGoal is to provide park and network specific air quality information.Identify location specific air quality impactsSummarize relevant studies and monitoring Links to available data sources

Idea! Lets provide all of the significant references too.Problem Dont want to build or maintain a database to store this information.

IRMA ConnectionsNRInfo already stores and manages reference informationMost of our key references were already in NatureBib and transitioned to NRInfoService oriented architecture allows for access to the databases supporting NRInfo from a public facing web page.

Search CriteriaProvide high quality air referencesPark/Network specific Sort by topicaerosolcontaminantsdepositionhazemercury

Establish our own reference setTie refs to locations in NRInfo Formalize key-words and add them to NRInfo records*ARD_Park-Air-Info_Collection

Data Set-upMore data considerationsEntering new citationsCheck for existing records first!Modify existing recordsOwnership = permission to edit key-words and locations.Making a reference visible on the webRef must be activated and made public in NRInfoInformation resource sensitivity must be set to Non-Sensitive this needs to be set for all legacy records imported from NatureBib or DataStore.

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

Emphasis on SimpleWant to be able to provide basic procedure + template code for interested parties7RESTRepresentational State TransferFielding (2000) Rest Constraints:Client-ServerStatelessCacheUniform InterfaceLayered 6. Code On Demand (Optional)

Returns a representation, or subset of data from NRINFO Reference ServiceFielding Doctoral Dissertation on Architectural Styles and the Design of Network-based Software Architectures

8BasicallyYou send a web request (URI) to get formatted data!

http://example.com?key={key}

All of the goals are taken care of by the fact that we are using the http protocol to retrieve data from NRINFO9NRINFO RESTNRINFO Reference Returns a Representation of Data in NRINFO databaseHere, its 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 ParametersFormat *Required Unit Code(s)Search FieldSearch StringStart IndexReference TypeBounding Area

Format The format of the returned results must be specified. Unit Code(s) One or more unit codes can optionally be specified. Search String One or more search strings can optionally be specified. Search Field If a search string(s) is/are specified, a single search field can optionally be specified. Start Index Since there are only 300 results returned, User can optionally specify the range of records to return. Reference Type A single Reference Type can optionally be specified. Bounding Area A single bounding area can optionally be specified.

Rocky B/c there are ~70 Units, using an XML file for the dropdown cuts down on the web page size15

SummaryActively getting freshest data from NRINFOReduce RedundancyData StorageUpdate

Future Work & PotentialAllow multi-select from drop down listsInclude download files when possibleUpdate GRI & ARD publications pages to draw from NRINFO

Improve efficiency of publication management Custom delivery of information on webpages More user-centric
