Open Source DAM at Historic New England
Historic New England’s mission We serve the public by preserving and presenting
New England heritage.
Historic New England is a museum of cultural history that collects and preserves buildings, landscapes, and objects dating from the seventeenth century to the present and uses them to keep history alive and to help
people develop a deeper understanding and enjoyment of New England life and appreciation for its preservation.
5 program areas
• Historic Properties • Collections • Preservation Services • Education • Library and Archives
Collections Access Project • Multi-year, grant funded effort
to enhance public availability of collections – New collections management
system – Large-scale digitization – New website
• Project plan did not initially include DAM
Existing Imagery • 20,000+ existing digital images of collections
identified before digitization even started
Increase in digitization capabilities
Contract digitization • ~1,400 slides of collection objects • ~8,000 microfilmed glass plate negatives from
Boston Transit collection • ~ 2,800 transparencies • ~5,000 black and white museum object prints • Etc…
Need for something!
• ResourceSpace – Open Source Digital Asset Management – Free! (as in puppies, not beer)
• Set up as low-commitment experimental tool • Use by collections staff drove acceptance as
permanent solution
ResourceSpace open source DAMs • Originally developed for Oxfam GB • Historic New England is using – and helping develop • Implemented for CAP, but now used across organization
ResourceSpace features
• 100% web based • PHP/MySQL technology • Support for a wide variety of file formats via
helper applications – Imagemagick – FFmpeg – Exiftool – Etc.
ResourceSpace features • Automatic creation of derivative images • Good support for embedded metadata • Configurable metadata by resource type
Permissions • Permissions can be set by user group, and can
also be overridden at the resource level
Collections
• Allow users to create arbitrary groupings of Resources
• Sharing – Internal users – External users via
time-limited URLs
Public collections
• Public collections – Available to all users – Linked from resource record – Show up in search results
• Themes – Curated collections of
resources
Collection contact sheets (PDF)
Alternate files
Transform Plugin • Allows users to create
custom derivatives – Crop – Set specific size – Rotate/Flip
• Multiple output options – Download – Save as alternate – Replace original
(with permission)
Filestore
• Filestore based on hierarchical folders within filesystem (users would never see this)
Storage
• Suse Enterprise server with two iSCSI NAS devices – ~5.4TB logical volume
• Planning for future expansion – Scalable storage system – Multiple servers talking to a single database?
• Solution for bulk image creation at two sites
Backup/Web: S3Sync
• Homebrew plugin mirrors filestore data to Amazon S3 – Offsite backup – Online collections
database images
• Bandwidth challenge – AWS Import/Export
partial solution
DAM/collections management integration
• ResourceSpace – SOAP server
implemented as plugin (PHP)
– Takes a resource ID and returns a filesystem path
• Minisis – Customization to allow
SOAP lookup rather than linking directly to file on disk
– Allows user to enter Resource ID and have image appear on cataloging record
DAM/collections management integration
• ResourceSpace
Minisis
Publication Export
• Allows users to gather groups of images, then export in “publication ready” format – Full resolution image – FPO – Manifest
• Long term: FUSE driver to expose collections directly on fileshare?
Import process
• Lightroom (or Phocus?) export presets to generate related names for different files
• Files go into hotfolder, picked up by customized version of ResourceSpace StaticSync script – StaticSync can operate in sync mode or ingest mode;
we use ingest
Import of embedded metadata
Import of embedded metadata
Geolocation
Used by entire organization
• Property Care Team – Imported 45,000 existing
images – Heavy creators and
consumers
• Web project • Training for various user
groups
DAM Survey
• Conducted survey of users, summer, 2010 – Approximately one year
after launch – 37 users completed survey
(55% response rate)
• Complete report available online – http://goo.gl/PNZxy
Need for system
Overall satisfaction with system
Overall Satisfaction
Areas for improvement
Supporting open source
• Active community of users/developers • PHP/MySQL programmers abound • Plugin Architecture
– customizations without changing core system
The tool is only the first step • Workflow planning • Policies & user training • Metadata standards and
practices • Monitoring of incoming
resources • Storage • Backup • Integration with other
systems
ResourceSpace resources
• Main Site – http://www.resourcespace.org
• Wiki – http://wiki.resourcespace.org
