Meeting Notes

DSpace Developer and DCAT Meeting Notes

Wiki page for the meeting: DevMtg 2015–06–08 – OR15 Meeting

  •  Building the ground work for strategic planning
  • DSpace is eleven or twelve years old – this is a good time to take inventory and begin to do strategic planning based on the last few years of planning
  • Planning has been done in a transparent way: all notes are on the wiki
  • Feedback needed

Maureen Walsh: Overview of 2014–2015 Strategic Plan

  •  Community and Sustainability plans are the least developed; if you want to get more involved, they could use your help
  • Goals focus on the next three years, but extend longer

Discussion on Community Goals

  •  Historically, DSpace has grown organically: if someone wants a new feature, it gets developed and contributed. It should be made clear that this roadmap is a departure from the way development has been done in the past.
  • We do have a very active userbase, a lot of people are contributing. How do we sustain that?
  • We are proposing that the model for DSpace development will have to change. We are proposing a much more managed process. We will be coordinating the work around releases and asking institutions to commit resources toward development sprints.
  • Why we think this will work: Fedora 4
  • We will need to change the rules for committers: as it is now, if enough committers agree on a feature, it gets in. Going forward, features should also be analyzed for whether they align with the roadmap.

Discussion on Sustainability Goals

  •  We need to be better at getting the message out: what is DSpace, what does it do, etc, what does it give you that others don’t?
  • The DSpace Marketing Group is working on putting together a draft marketing plan, which will be completed in a couple months
  • Product Manager role is promotion of the product overall: outreach, gathering use cases, fund raising, etc.
  • Currently looking for resources to fund a full-time Product Manager
  • If you are in a position that you can make a personal appeal to a non-member, DSpace-using institution to join, then please do

Discussion on Technology Goals

  •  No plan for a complete DSpace rewrite, but a UI rewrite would be OK
  • What are the fundamentals of the modern IR use case? What do we need to focus on?
  • 130 or more use cases have been gathered and are being analyzed and prioritized
  • These use cases drove the development of the road map
  • Agility and flexibility are paramount goals
  • Feedback is needed
  • Non-developer DSpace end user comment: excited to see the proposed changes
  • DCAT meeting is 2nd Tuesday of every month; all are welcome to join the call
  • UI rewrite is the most significant: it is the most customized locally and will require a lot of support for adoption
  • A lot seems to be riding on the future Product Manager; we shouldn’t rely on them to solve these problems for us; we need to support them
  • The earliest we can get the PM would be 2016
  • There is no way to get around the problem of having two UIs
  • Need to be reassured that the new interface will
  • Who will do the UI work? There needs to be a full-time developer paid by DuraSpace.
  • Several institutions have already promised resources to get this done. We think there are enough people lined up now to accomplish our goals
  • What features will be moved out of the core functionality?
  • We have some use cases that we have deemed high priority. One feature that will be moved out of the core is one of the duplicate statistics modules

Tim gives a brief version of his roadmap slide presentation. More will be discussed at the Thursday session.

Notes on roadmap presentation

  •  Concentration will be on the next two releases: 6 and 7
  •  c.f. RoadMap wiki page
  • Anonymous feedback can be given on the wiki
  • DSpace 6.0 will be the last ad-hoc-development release, but with an eye to the roadmap; 7.0 will be roadmap driven
  • 7.0 will be late 2016 / early 2017
  • Need to start planning immediately!


  •  Idea: Virtual collections based on a search query. What is a collection other than a tag? What does it mean for something to be in a collection?
  • There are wiki pages for each of the priority use cases
  • API seems to be conspicuously missing. Is the idea that the new user interface will interact with a Web API that supports the entire suite of - - DSpace interactions
  • Part of the agenda is to figure out what is missing in the current REST API. We will need to fill in those gaps.
  • This is the time to make the API the canonical way to interact with DSpace
  • Single UI will be a massive job; API will be another massive job; if I were to focus on one massive job, it would be the API
  • Top down or bottom up?
  • Developers agree that the core business logic is where we want to be.
  • What is the difference between refactor and rewrite?
  • Refactor can be done incrementally, whereas a complete rewrite would have to happen “behind closed doors” until it is completed
  • Fedora did a lot of new development, which was a risky venture albeit a successful one
  • Difference between us and Fedora: The Fedora group had enough resources, with committed institutions contributing $30,000. Fedora has about 250 institutions; DSpace has over two thousand. We need to figure out how to best harness that large user group, particularly from non-North-American institutions
  • How can we reach out to the non-USA institutions?
  • Mostly around what’s going on in the UK: everything we are doing around repositories is in preparation of the open access ref
  • Need to come back to the definition of contribution; in-kind contributions is a way forward; suggest we don’t close the gate on random, ad-hoc improvements
  • Can DSpace try to work more with the European funding models
  • Repositories have changed since DSpace stared. We use it for a lot more things nowadays. DSpace has to be a place for other kinds of content
  • Is DuraSpace able to accept smaller contributions? Full membership is a challenge.
  • Is there marketing material for how to convince your boss to support DSpace?


Notes on the roadmap presentation (cont.)

  • Integrations to lower effort to deposit - 
  • Priority selection for 7.0 - Top priority items depend on whether there are developers available, not feasible to make everything priority 1
  • Priority 2 - recommended for 7.0 but dependent on contributors
  • Hierarchical metadata, MODS
  • Enhanced basic statistical reports - based on data already available, but not already surfaced; use cases have been collected 
  • Basic preservation - format recognition, checksum tracking; potential advanced integration use cases, such as migration
  • Easy and intuitive deposit UI - still collecting use cases for this, high priority but not developed enough yet
  • Beyond 7.0 - priorities
  • Simplify installation and upgrade - some work done on this, but more work to do; may be dependent on modularisation of DSpace hence lower priority right now
  • Theme management - once single UI has been developed, focus could 
  • Replacing "bundle" with metadata flags on bitstreams
  • Prioritised integrations - dependent on UI framework

How will we achieve this?

  • Managed projects - based on part time, donated developers with scheduled (1-2 week) development sprints
  • More volunteers/contributors needed to achieve this; some organisations have stepped forward already but get in touch

DSpace Single UI - 7.0 release late 2016

  • Prototype (at least) 2-3 UI platforms
    • at least 1 Java-based
    • at least 1 non-Java
  • By the end of 2015 intention to approve a single platform/prototype and finalize the developer team/schedule
  • Early 2016 - developer sprints begin in readiness for a 7.0 release


  • 3 UIs in prototype but only one will go forward as the new UI for 7.0
  • Clear path for moving to new UI for users
  • Need input from the DSpace community early 
  • Make the process as open as possible 
  • Goal at OR2016 would be to present some kind of beta
  • Resources for testing will be stretched and a lot of effort from committers with testing for 6.0 candidate, plus work on prototype
  • Prototyping may have to be done by people who are not committers
  • Need to scope now what 6.0 release contributions are with an earlier cut off 
  • Suggestion that 6.0 could be a larger bug fix release and hold off major changes to UI based on potential single UI in later release
  • Does there need to be a 6.0 release this year? 
  • There was some discussion about this in the roadmap meetings
  • Feeling was that there are things that institutions would like to get into 6.0 as soon as possible 
  • There is some development in process around the API (question) on the 6.0 status page - Atmire have been developing this
  • High risk not to do a 6.0; roadmap is speculative at the moment, and targeted for end of 2016 but this cannot be promised potential for a big gap between major releases
  • More people really needed, not just for members, but also developers/contributors who can help and also test
  • More contributors fundamental to the roadmap

Other 7.0 priorities

  • Projects will be established for these with a similar development model as the single UI project, not as developed at the moment
  • Mentoring may be possible to build on the committer team and bring on developers/contributors to become committers

How you can help

  • Become a DuraSpace member
    • Helps toward hiring a Product Manager
    • Voice in DSpace governance & roadmap
  • Donate a developer (part time)
    • choose a project
    • get in touch
    • sprints get scheduled by DuraSpace


  • Acknowledgement of the amount of work that has gone into developing the roadmap and strategies
  • Support for open discussion and use of DCAT - this would be continue for future projects

DSpace 6.0 planning

  • 6.0 status page - DSpace Release 6.0 Status
  • Highest priority is to clean up search/browse
  • Basic priorities have been identified
  • Atmire - a few open issues on JIRA that Atmire are working on, should be resolved through work being undertaken with Sydney at the moment
  • Collection quality control management has been requested by Georgetown
  • Rough list at the moment
  • Pull request nearly ready for the OAI harvester  - CottageLabs
  • 'Code Review Needed' - flagged items mean that something is ready for testing and developers would be interested in feedback
  • Texas A&M - SAF (Simple Archive Format) builder working with batch loading, added capabilities for special licences
  • DSpace Labs project - cool tools that have been developed/under developed where people can go and test these and also work collaboratively
  • Licences - access control licences, specifically for datasets where need special licence request that prompts login
  • Special agreements page 
  • Command line utility for reporting
  • More contributions welcome for the REST API - gaps to be identified
  • More use cases very welcome - there are lots there already
  • None of the use cases cover 'Review'
  • Add new use cases using the template here: Use Cases, also add to and comment on current use cases


  • What is the migration status of DCTerms? - DCTerms schema came with version 5.0 (in addition to Dublin Core)
  • What is the plan for completing migration to DCTerms from Dublin Core? 
  • Ticket for this work open in JIRA  DS-1927 - Getting issue details... STATUS

  • DSpace-general - list is very busy and easy for things to get lost; suggest that questions be moved to Stack Overflow -


  • IRC - is there intention to move to web/audio meetings?
  • IRODs - is there current integration for this for Dspace? EUDAT have been working on something in this area
  • Integrations - is there somewhere that we can survey and record who is working on specific integrations?  Such as a Google Spreadsheet? Suggestion to contact DCAT in the first instance and then look at ways to survey the community
