OpenVista Interface Domain

The OpenVista Interface Domain (OVID) layer is a set of development tools designed to enable software developers easier access to OpenVista data. Currently, we've implemented a set of java domain classes that demonstrate how this can be accomplished.

If you've ever wanted to call an OpenVista RPC from java, then this tool would be of interest to you.
If you've ever wanted to construct a fileman call in java because you can't find a suitable, existing RPC, then OVID would be of interest to you.

OVID is basically an RPC resource messaging interface with java bindings. OVID can execute an RPC and get the results. It is up to the developer to construct the call and glean the results into a usable format. Further, OVID contains mumps routines and a specialized RPC that can invoke Fileman on behalf of the caller. RPC and Fileman "modes" can be easily intermixed.

Included in this release is a sample application. This Patient Dashboard application is meant to provide an example of using OVID as a data provider for a web-based application. In this case, the developers were able to quickly build this application by using OVID to build an API that accesses existing data and RPC calls. The OpenLaszlo-based Patient Dashboard is described in the Dashboard Release Notes.

FileMan Query Language (FMQL) v0.9 now available in OVID

Posted by Ben Mehling Jul 7, 2011

CareGraf announced a new release for FMQL:

The latest FMQL (FileMan Query Language) has just posted on caregraf.org (http://www.caregraf.org/semanticvista). FMQL let's you query any and all data in a VistA EHR.

Some highlights of this release:

all web-clients use the latest HTML5 standards and still support IE 7
"Query Maker", a new "click and query" web client for learning how to create FMQL. The FileMan Rambler client has fully query exposure too.
improved VistA vocabulary management to leverage version 2 of Caregraf's public datasets (see below)
fine-grained control for walks through deep and wide containment hierarchies
improved paging support for walking larger files
improved projection of lab package data: lab data now looks like any other information in FileMan

FMQL is completely open source and can be seen in action and downloaded from http://www.caregraf.org/semanticvista

*** coming Monday July 18th: the next chapter for Caregraf's Public Datasets (http://www.caregraf.org/datasets), medical vocabularies published as linked-data to promote patient data exchange. The emphasis is on SNOMED and the VA's national vocabularies and, through FMQL, VistA is fully integrated.

Mobile access to OpenVista via iPhone in OVID

Posted by Ben Mehling Jun 6, 2011

Hugo Toche has released an updated mobile EHRAccess application for the iPhone via the Apple iTunes Store. It is free to download and use.

With this application you can securely access the patient data in your OpenVista system. All you need to do is install the OpenVista REST module and point the application to it via the server field in the login screen. This is where you can get the open source OpenVista REST module. No data is kept on the device for security purposes.

Hugo is active here on Medsphere.org, so feel free to ask him questions or provide feedback. You can also view his other mobile applications at Troche Labs.

OVID 1.1.2 Released in OVID

Posted by Ben Mehling May 24, 2011

We are pleased to announce OVID 1.1.2 has been released. We would like to offer our thanks and appreciation to the MITRE Corporation who worked with OpenVista and OVID as a part of their MedCafe.org research, and generously contributed their changes back to the community.

Highlights of the updates in this release:

MSCVJAVA developer utility creates FM java class from FileMan schema
Enhanced Patient Medication class
Enhanced Patient Repository class
Ability to Create and Sign notes, as well as add additional Signers

Thanks to the hard work and generous contributions by the MITRE Corporation, a number of new and enhanced repositories were added. This work was done as part of the MedCafe project, a research effort designed to explore the viability of specific system design principles for EHR access. The developers used OVID as part of their data access strategy and in the process created and enhanced the available repositories that are released with OVID. Thanks to their contributions, we have incorporated that work back into the OVID mainline for this release.

Ability to Add and Update a patient
The PatientVisit domain was greatly enhanced to include:
- CPTs
- Diagnosis
- Name Components
- Religion
- Room-Bed
- State
- Exam
- Health Factors
- Immunizations
- Patient Education
- Purpose Of Visit
- Provider
- Skin Test
- Treatment
- and more
The PatientAllergy domain was enhanced to support the Addition and Update of patient allergies, as well as data from the following areas:
- Drug Class
- Drug Ingredients
- Generics
- Allergies (GMR, Patient and Comments)
- Symptoms

OVID 1.0.0 released in OVID

Posted by Andy Pardue Mar 16, 2010

We've recently updated the ovid source project in Launchpad to integrate several enhancements and bug fixes that have been developed over the last few months. Included in this release:

@FMAnnotateFieldInfo annotations can now be placed on getters as well as on class variables.
OVID supports inheritance to an extent. Note the FMPatientContact extends FMDemographicPatient, which extends FMPatient. Each class adds new fields along the way. This makes it much easier to extend existing behavior.
Bug fixes and enhancements to the mumps routines are provided in two new KIDS buids: MSCRES.1.3.KID and MSCFM.1.3.KID.
Some additions to existing domains are included, such as RaceInformation tied to an FMPatient. (See PatientRepository.java).
Of course, general bug fixes are also included in the java sources.

This release should be backwards compatibile to any projects developed against previous version of OVID. It is recommended that you apply the new KIDS builds and drop in new ovid.jar and ovid-domain.jar.

Installation instructions can be found at http://medsphere.org/docs/DOC-1719.

Don't hesitate to post questions and/or suggestions to the OVID project.

Please submit bugs to https://launchpad.net/ovid.
