New Tools for a BetterAir Quality System Data Flow

EN 2012May 31, 2012

• Air Quality System (AQS) flow automation enhancements

• Exchange Network Services Center• AQS Plugins for OpenNode2 and EN-Node• Q&A / Discussion

Topics to Cover

• 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

Jumping Through Hoops

Can I interest you in an AQS data flow?

• 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

Fewer Flaming Hoops…More Puppies

Perhaps this is more to your liking?

• 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

How Does it Work?

The submitter defines the desired level of automation:

1. Stage: Submission file is uploaded to the AQS server and verified to be a valid AQS file type, but with no subsequent processing.

2. 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”.

3. Post: All valid sample measurement data for the file is set to the status “Production”.

– Post is the default setting

AQS Load Options

• Exchange Network Services Centerhttps://enservices.epa.gov/login.aspx –Automatically creates EN Header–Supports manual submissions to AQS–Replacing CDX-Web for AQS submissions

New Submission Option #1

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.

• 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 AirVision1. Submit AQS data to EPA2. Publish AQS (Query)3. Publish AQS (Solicit)

Minimum Data Needed

Before Configuration…

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

• Create AirVision domain – Choose web services (Submit, Download, Query, Solicit, Notify) allowed for

the domain.

• Establish “Administrator” accounts to setup/modify this domain.

Step 1: Create Domain

• Register Operation(s)1. Submit AQS data to EPA: Task_SubmitAQSXMLData_DataWizardConfig.xml2. Publish AQS (Query): Query_GetAQSXMLData_DataWizardConfig.xml 3. Publish AQS (Solicit): Solicit_GetAQSXMLData_DataWizardConfig.xml

Step 2: Register Operation(s)

Define•EPA Endpoint URL•Validation rule (if any)•Data viewing stylesheet (if any)

Define•Task schedule

• Register Operation(s)1. Submit AQS data to EPA: Task_SubmitAQSXMLData_DataWizardConfig.xml2. Publish AQS (Query): Query_GetAQSXMLData_DataWizardConfig.xml 3. Publish AQS (Solicit): Solicit_GetAQSXMLData_DataWizardConfig.xml

Step 2: Register Operation(s)

1. 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

Step 3: Test Operation(s)

Authentication

Query Request

2. Test AQS Data Query– Authenticate – Input Start Date and End Date for AQS

monitoring date– Query will return data in XML

Step 3: Test Operation(s)

Authentication

Solicit Request

Get Status

Call Download

3. Test AQS Solicit– Authenticate – Solicit (Input AQS monitoring date)– Get Status– Download AQS data (in XML)

Step 3: Test Operation(s)

• 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

Step 4: Publish AQS Data at ENDS/ENB

3. Submit Data

1. On a set schedule (or manually triggered), request data from AirVision or DrDAS• Parameters set to filter data request

2. AQS XML data is returned to OpenNode23. Relay the data to EPA CDX/AQS system

• Optionally, header is added• Optionally, notifications can be sent

Status Response1. Get Status

Files2. Download Request

3. Notifications

1. On a set schedule (or manually triggered), check status of outstanding submissions

2. If CDX returns “completed” or “failed”, download processing reports from CDX• Do nothing if status is “pending”

3. Optionally, send notification emails to agency staff1. Mail sent for all submissions where status

changes from “pending” to “completed” or “failed”

• “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

Publishing AQS Data from OpenNode2

Setting up the AQS Plugin/Flow

• Very similar to setting up any other OpenNode2 data flow

• Using the Node Admin interface:1. Create the AQS flow2. Upload the plugin (contains all workflow logic)

3. Configure the Services (exposes plugin logic)a) Service 1: Get data from AirVision/DrDAS for submission to EPAb) Service 2: Check status of submission and download results

4. Create the Schedules (automates workflow)

… and that’s it for the OpenNode2 portion
