  1. New Tools for a Better Air Quality System Data Flow EN 2012 May 31, 2012

  2. Topics to Cover • Air Quality System (AQS) flow automation enhancements • Exchange Network Services Center • AQS Plugins for OpenNode2 and EN-Node • Q&A / Discussion

  3. Jumping Through Hoops • AQS submissions via a Node or Node Client used to require extra manual steps • More difficult to access AQS submission logs and reports • Most users preferred to use EPA’s non-Exchange Network interface called CDX-Web Can I interest you in an AQS data flow?

  4. Fewer Flaming Hoops…More Puppies • Today, files submitted through the Exchange Network are automatically processed by AQS • Exchange Network Nodes can download the submission log and reports • New tools for submitting AQS data via the Network • Support for AQS submissions through CDX Web is being discontinued Perhaps this is more to your liking?

  5. How Does it Work? • AQS data flow (v2.2a) now uses the Exchange Network Header • The Header file contains information about the submission data file • Security Token • Exchange Network and AQS User IDs • Payload type: 1) XML or 2) FLAT • AQS Load Options • Final Processing Step • Stop on Error

  6. AQS Load Options The submitter defines the desired level of automation: • Stage: Submission file is uploaded to the AQS server and verified to be a valid AQS file type, but with no subsequent processing. • Load: The file is loaded into the AQS database and its contents validated. Sample measurements are left at the status “Pre-production”; all other data types (Site information, Monitor information, and QA information) are set to the status “Production”. • Post: All valid sample measurement data for the file is set to the status “Production”. • Post is the default setting

  7. New Submission Option #1 • Exchange Network Services Center https://enservices.epa.gov/login.aspx • Automatically creates EN Header • Supports manual submissions to AQS • Replacing CDX-Web for AQS submissions

  8. New Submission Option #2 Node Plugins for OpenNode2 and EN-Node • Customized for easy integration with 2 widely used air monitoring systems • OpenNode2 - .NET – AirVision and DR-DAS • OpenNode2 - Java – DR-DAS • EN-Node - .NET – AirVision • EN-Node – Java - AirVision • Automatically create EN Header • Support submissions to AQS and data publishing • In testing. Production-ready versions likely available in June for free download from EN website.

  9. Show and Tell • Exchange Network Services Center • EN-Node Plugin • AirVision • OpenNode2 Plugin • AirVision & DR-DAS

  10. EN-Node AirVision Plugin • AirVision Plugin Features  3 Operations Submit AQS data to CDX Publish AQS data (Solicit) Publish AQS data (Query)

  11. Installation File & Contents • URL: http://code.google.com/p/en-node2/downloads/list • File: AirVisionPlugIn.zip

  12. Configure AirVision Plugin • What is Configuration? • Business logics used by EN-Node to complete the data flow • Config. data saved in an external BEPL file (Business Process Execution Language) • Each Operation has its own BEPL file • Configuration tools • EN-Node Admin Console • BEPL XML file provided with the Plugin installation file • How to Configure: Step 1: Create a Domain (AirVision) Step 2: Register 3 operations under AirVision • Submit AQS data to EPA • Publish AQS (Query) • Publish AQS (Solicit) Step 3: Test Plugin Step 4: Publish AQS data at ENDS or EN Browser

  13. Data Needed to Configure AirVision Plugin Minimum Data Needed Plugin Configuration Options • AirVision End Point • EPA AQS End Point • Organization Name • NAAS ID & PWD • Plugin file location

  14. Before Configuration… Important! • Open 3 DataWizardCinfig.xml files with text editor • Enter Plugin file location

  15. Step 1: Create Domain • Create AirVision domain • Choose web services (Submit, Download, Query, Solicit, Notify) allowed for the domain. • Establish “Administrator” accounts to setup/modify this domain.

  16. Step 2: Register Operation(s) • Register Operation(s) • Submit AQS data to EPA: Task_SubmitAQSXMLData_DataWizardConfig.xml • Publish AQS (Query): Query_GetAQSXMLData_DataWizardConfig.xml • Publish AQS (Solicit): Solicit_GetAQSXMLData_DataWizardConfig.xml • Define • EPA Endpoint URL • Validation rule (if any) • Data viewing stylesheet (if any) • Define • Task schedule

  17. Step 2: Register Operation(s) • Register Operation(s) • Submit AQS data to EPA: Task_SubmitAQSXMLData_DataWizardConfig.xml • Publish AQS (Query): Query_GetAQSXMLData_DataWizardConfig.xml • Publish AQS (Solicit): Solicit_GetAQSXMLData_DataWizardConfig.xml

  18. Step 3: Test Operation(s) • Test Submit AQS to EPA • Test: Enter Start Date and End Date to a date earlier than the current date will execute task after the user clicks save. • Track submission status • CDX will return “Completed” or “Failed” • View • Download • Data Viewer

  19. Step 3: Test Operation(s) 2. Test AQS Data Query • Authenticate • Input Start Date and End Date for AQS monitoring date • Query will return data in XML Authentication Query Request

  20. Step 3: Test Operation(s) 3. Test AQS Solicit • Authenticate • Solicit (Input AQS monitoring date) • Get Status • Download AQS data (in XML) Authentication Solicit Request Get Status Call Download

  21. Step 4: Publish AQS Data at ENDS/ENB • Manual data input to ENDS: • Test: https://ends2.epacdxnode.net • Production: https://ends2.epa.gov • XML Data Upload to ENDS: • Auto Pull from ENDS: GetServices • Manual XML Upload to ENDS • Test: https://ends2.epacdxnode.net/Node2WS.svc • Production: https://ends2.epa.gov/Node2WS.svc • Dataflow: ENDS_v20 • Operation: Service Refresh

  22. Useful Tips for EN-Node AirVision Plugin • Implement Only the Operation(s) you need • Minimum data you need to configure Plugin • AirVision End Point • EPA AQS End Point • Organization Name • NAAS ID & PWD • Plugin file location • Useful resources • Plugin: URL: http://code.google.com/p/en-node2/downloads/list • Data Publication Guide: http://www.enbrowser.net/enbrowser/ClientBin/HowToPublishData.pdf • ENDS & FCD: http://www.exchangenetwork.net/2011/07/15/exchange-network-discovery-service-ends/ • Support • enfoTech, Lijie Xu: lijie_xu@enfotech.com

  23. Show and Tell: OpenNode2 AQS v2.2 Plugin

  24. OpenNode2 AQS v2.2a Plugins • http://code.google.com/p/opennode2 • .NET OpenNode2 • AirVision • DrDAS • Java OpenNode2 • DrDAS

  25. OpenNode2 AQS Submit Workflow AirVision Or DrDAS Web Service OpenNode2 EPA CDXNode 1. Request Data 3. Submit Data 2. Return Data • On a set schedule (or manually triggered), request data from AirVision or DrDAS • Parameters set to filter data request • AQS XML data is returned to OpenNode2 • Relay the data to EPA CDX/AQS system • Optionally, header is added • Optionally, notifications can be sent

  26. Get Status/Download Workflow OpenNode2 EPA CDX 1. Get Status Status Response 2. Download Request 3. Notifications Files • On a set schedule (or manually triggered), check status of outstanding submissions • If CDX returns “completed” or “failed”, download processing reports from CDX • Do nothing if status is “pending” • Optionally, send notification emails to agency staff • Mail sent for all submissions where status changes from “pending” to “completed” or “failed”

  27. Publishing AQS Data from OpenNode2 • “Publishing” makes data available for any authorized partner to come and query from your node • Exposed as Query and/or Solicit services • No additional setup needed to make these services available from OpenNode2 • Setting up the services in Node Admin tool makes them available with a simple checkbox

  28. Setting up the AQS Plugin/Flow • Very similar to setting up any other OpenNode2 data flow • Using the Node Admin interface: • Create the AQS flow • Upload the plugin (contains all workflow logic) • Configure the Services (exposes plugin logic) • Service 1: Get data from AirVision/DrDAS for submission to EPA • Service 2: Check status of submission and download results • Create the Schedules (automates workflow) … and that’s it for the OpenNode2 portion

  29. OpenNode2 AQS Service Setup View in Node Admin of AQS flow with services configured: Flow 1 Service 1 Service 2 Flow 2 Service 1 Service 2
