Welcome to Sahana Agasti's "Vesuvius" Branch

Vesuvius continues a lineage from Krakatoa, and is being developed further primarily by the US National Library of Medicine (NLM). This effort is mainly concerned with improving family reunification and administrative capabilities, developing a robust code base, and exploring mobile technologies. The project is driven by international responses such as the Haitian earthquake of 2010, and US-hospital-focused triage needs. Some modules inherited from earlier have been recently deprecated as not supported by NLM, and removed from the trunk into an external branch. (Interested doing the programming needed to bring particular ones back to life for Vesuvius? NLM will be happy to work with you.) Other modules are new, or represent a substantially re-engineering of earlier work. During the Google Summer of Code 2010, Vesuvius was used as a testbed for prototypes of a Module Manager and Sahana App Store.

Created in response to the 2004 tsunami, Sahana built a web site using the PHP programming language. Capabilities were expanded during “Phase 1” releases, 0.1 to 0.5. These releases were superseded by “Phase 2”, as 0.6.x. By 2009, this was bifurcated into a “stable” branch and a more-experimental trunk branch, which eventually was known as 0.9.x. In mid-2010, a new nomenclature was adopted. Active branches of “Agasti”, the part of Sahana based on PHP web technology, were given the names of well-known volcanoes. The “stable-0.6” branch was recast as “Krakatoa”. New development subsequently took two forms:

• “Vesuvius” continues the major evolution of selected parts of the 0.9.x trunk branch (now moving towards 1.0). It introduces database referential integrity and more object-oriented code libraries. It is available to developers in unpackaged form from the repository, with packaging planned.
• “Mayon” (designated 2.x) restructures Sahana functionality, based on the Symphony PHP framework. This is described elsewhere.

In January, 2011, Vesuvius was slimmed down, and made of more-focused functionality, by removing from the trunk repository those modules lacking support, and thus deprecated. All the code for these is still available elsewhere, if someone wishes to revive them.

Check out this diagram of the "Genealogy of Vesuvius" during 2010-12, and some ideas for its further evolution in 2013. It covers People Locator and Kilauea.

Currently, most Vesuvius 0.9.x beta development goes on in-house at NLM. The code has been pushed to Launchpad/Vesuvius, where it is appropriately spread amongst the various Bazaar branches therein. See the preliminary checklist for accessing the codebase and working with Bazaar.

Packaged releases with an installer are anticipated during 2012; some final work must first be completed on the last few remaining bugs in the installer. A preliminary page for Vesuvius installation information has been created.

Developments in this project are reported to the sahana-agasti listserv, and through periodic postings to the unofficial Lost Person Finder blog, among other places. The freenode IRC channel #sahana-agasti facilitates cross-fertilization between Vesuvius and Mayon.

Vesuvius Installation Instructions

Sahana has been selected as one of the mentoring organizations for Google Code-in (GCI) 2012. GCI is an annual competition hosted by Google to involve pre-university students from around the world with reputed Open Source communities.

• Sahana Vesuvius Task Ideas page for GCI 2012: Ideas for Google Code-in 2012

For US citizens and permanent residents, there are competitive paid internship opportunities for local high school, undergrad, graduate, and post-docs on-site at NLM. Volunteer positions are also possible. We are looking particularly for folks with programming experience. Besides the Lost Person Finder project, our branches of NLM (Communications Engineering Branch and Computer Sciences Branch) have a number of other projects; those with coursework or experience in image processing, document understanding, and natural language understanding are particularly invited to consider us.

Summer student positions at NIH are applied for in January/February of each year. We at NLM will review applicants but only after they have submitted their NIH application.

• The Modules of Vesuvius

• Owen Royall-Kanih worked with an NLM instance of Google's open-source Person Finder, as a testbed for PFIF import/export, plus developed new-event alerting code, contributed back to Google.
• Michael Bulgakov developed missing/found-person artificial-data generators.
• Returning student Chase Bonifant created system diagrams and documentation, improved NLM's internal project website and wiki, and (during winter break of 2011/12) organized a draft continuity of operations plan.
• Joy Frazier documented the triage process, and investigated applicability of social media/crowd-sourcing tools.

• Ramindu Deshapriya worked on Pootle Re-integration and Multilingual Support
• W. A. Chinthaka Rukshan Weerakkody developed a Shared Installer (jointly with Mayon)

• Kusum Madarasu developed a Module Manager for Vesuvius. Kusum was mentored by Greg Miernicki, Glenn Pearson, and Chamindra de Silva.
• See also: the related Sahana App Store concept, that Kusum experimented with.

Volunteer Developers working with TriagePic:

• Emad Ibrahim integrated a Webcam View/Image Capture window.
• Jeff Bobish added a picture viewer to the Outbox.

Volunteer Developers working with ReUnite:

• Vicky & Ryan Somma rapid-prototyped an Android version.

Also helping with concepts and contacts: Kumar Rangasamy & Ari Kaliannan

• Chase Bonifant developed large-format system and workflow diagrams.
• Hyen Guan prototyped image duplication and face detection software.
• Bathiya Senevirathna created and improved the “Found in Haiti” iPhone app, later called “ReUnite”.

• Merwan Rodriguez - PL Graphical user interface, Ajax (particularly filters, results popups), SOLR search engine and MySQL search through September, 2011;
• Anantha Bangalore - Bluetooth R&D, Haiti earthquake meta-search, through July, 2010.
• Ajay Kanduru - Haiti earthquake screenscrape from CNN iReports, initial SOLR integration

Source code for the above PeLo modules is available on Launchpad. Additional experimental or student modules, not integrated into the trunk at this time, can be found in other repository branches. Some NLM work under active development has not yet been pushed to the trunk.

Bug reports are also handled on Launchpad.

NLM's involvement with Sahana began in 2008, through one of a group of projects for the Bethesda Hospitals Emergency Preparedness Partnership (BHEPP). October, 2009, saw the first alpha pilot by BHEPP during the CMAX 2009 exercise. A further iteration was tested again a year later during CMAX 2011.

Over time, additional appropriate “Phase 2” content will be moved here and freshened. For now, go to phase2.
