Work in progress for the upcoming VIVO 1.8 release

Projected Release Timing

One outcome of the meeting of VIVO sponsors at the March, 2014 DuraSpace Summit even in Washington was a request to move to a regular release schedule where timing would be predictable and new features included only if ready.  Any feature not on target to be finished by the code freeze data would have to be deferred until the next release.

A schedule of two releases per year targets a May code freeze for a June release (VIVO 1.7), and a November code freeze for December release.

The VIVO 1.8 release is being was originally delayed to allow completion of a task that has been deemed essential for moving the VIVO project from incubator to full project status – replacement of the Pellet reasoner (VIVO-778).

With that work complete before the holiday break, additional performance-related improvements were prioritized for early January:

Release Mechanics

The VIVO project uses the DuraSpace JIRA issue tracking system to manage issues and time tracking leading up to any given release.  Issues are categorized as bug fixes, tasks, code tasks, or improvements, grouped into components such as ontology or testing or technical debt, and assigned a status based on criticality to the release.

The issue tracker is publicly viewable but to comment you need to sign up for a user account with DuraSpace.  Accounts are shared between the DuraSpace wiki and issue tracker but the different DuraSpace projects including DSpace, Fedora, and VIVO each have different permission groups for access to project-specific wiki and JIRA spaces.  Send us a note to be added to the VIVO wiki and JIRA spaces.

View unresolved and recently-modified issues for the v1.8 release. Note that issues are typically written as specifically as possible to provide clear requirements to developers and allow for realistic time tracking; when it makes sense, more detailed tasks are grouped as sub-tasks of a more general summary task.

When all issues marked with a status of blocker have been resolved, a code freeze is declared and a release candidate is prepared to allow Selenium (acceptance) testing to beginfor conducting acceptance testing, primarily with a set of Selenium tests. Most releases include require several iterations of release candidates and testing to address problems detected in testing.

VIVO

...

• pointed out by Eliza in testing with Virtuoso
• a maxCardinality property was being specified as a non-negative integer but was stored as an integer, so on startup the TBox reasoner interpreted an ontology change
  • saw the same thing in Virtuoso and TDB, but doesn't show the problem with SDB
    • got around it with a kluge to the Virtuoso driver – would like to distribute with that patch if can't get around it
  • worth a couple more hours to pursue – may be an issue in the general RDFService code, that is not used for SDB
• steps to address this may also shave more time off the startup time

Other general goals

• Modularization
  • Major pieces of the application are selected at startup, based on a configuration file.
• Improvements in display
• Model handling
  • Technical debt: all access of triples goes through two parallel sets of channels (content and configuration)

• Wiki restructuring
• Customization guide

VIVO-ISF ontology

Ontology issues for VIVO v1.8 have been managed in 3 places as the community workflow process evolves.

1. Within the primary DuraSpace VIVO Project JIRA space
2. In a older, now-deprecated DuraSpace VIVO Ontology JIRA space (a decision was made in 2014 to stop segregating ontology issues specific to VIVO from the main VIVO project JIRA space 
3. In a tracker on GitHub, where VIVO-specific issues have been tagged with "question"

Documentation

Documentation issues for VIVO v1.8 are managed using the community/documentation component within the primary DuraSpace VIVO Project JIRA space.

Testing

Acceptance tests for VIVO v1.8 are managed using the testing component within the primary DuraSpace VIVO Project JIRA space. Additional issues related to testing be found by searching for "test" among the issues assigned to version 1.8 that may be listed under components such as technical debt or bug fixes.
