- 8. Why DSpace?
- 9. About DSpace DSpace supports many file formats, but historically has lacked good support for presenting and sharing digital objects online. Within the DSpace community interest in IIIF has existed for several years. Both local and commercially-supported solutions (4Science) have been created. A IIIF integration is now officially distributed as part of DSpace 7.
- 10. Integrating IIIF in a Digital Library Environment Since 2017, 4Science has been working at: - integrating IIIF in a Digital Library environment based on DSpace, developing a dedicated addon (starting from version 5), easily integrated with a set of external Image Servers, such as Cantaloupe or Digilib
- 11. Together we can WILLAMETTE UNIVERSITY BEGUN WORKING ON DSPACE 7 AND IIIF FOR ENHANCING ACCESS TO THEIR DIGITAL CONTENTS 4SCIENCE AND WILLAMETTE UNIVERSITY COLLABORATED TO BRING IIIF TO THE DSPACE COMMUNITY
- 12. DSpace 7 and IIIF together • Thanks to the fundamental support of Willamette University in 2021 IIIF support was implemented in DSpace 7 • DSpace 7.1 Release: October 2021 • Initial IIIF support: Presentation API 2.1.1, Image API 2.1.1, Search API (experimental), Mirador 3.
- 13. DSpace and IIIF together • Now the DSpace 7 IIIF support allows institutions to upload images in DSpace getting automatically a IIIF manifest for the item, based on item and bitstream (images) level metadata.
- 14. Driven by metadata IIIF configuration at the Item- level is quite flexible and is managed using metadata. Canvas sizes, image labels, ranges and and other settings are controlled by using the following fields. The dspace.iiif.enabled metadata field MUST be added to the Item and set to "true". Otherwise, the Item display will use the default DSpace view.
- 15. Driven by metadata (Item level)
- 16. Driven by metadata (Bitstream Level) Structural metadata (optional) Canvas dimensions (recommended)
- 17. Embedded Mirador viewer • Viewer layout is defined in the default Mirador configuration. • Search options are added dynamically based on Item metadata. • Support for indexing OCR files is not currently provided by DSpace. Institutions will need to develop their own approach to indexing their data.
- 20. Using the Search API
- 21. Comparing different contents on the Virtual Desktop
- 22. Comparing Digital Objects on the Virtual Desktop Experience an immersive journey outside repositories boundaries.
- 25. Web Annotation
- 26. DSpace and Digital Libraries • Actually implementing IIIF is a fundamental achievement in DSpace history, since it is going to promote its use in contexts such as those related to scientific field and digital cultural heritage management • However digital images management is only a first step since Digital Libraries are getting complex and complex
- 27. Digital and the fragmentation risk "Where is the wisdom we have lost in knowledge? Where is the knowledge we have lost in information?" Where is the information we have lost in data ?
- 28. Digital Libraries are the main tools, in the Humanties, for arriving at re- composing knowledge and at extending it
- 30. Digital Libraries in the 21st century • Digital Libraries should not be considered as mere lists of items grouped into collections • They are tools allowing the definition of relationships on different scales and according to different variability dimensions, in order to reconstruct digital cultural landscapes • A document can be explored and analyzed in relation to other documents and to all the information helping to define its context, or rather its different contexts (historical, geographical, cultural, etc.)
- 31. DSpace-GLAM • To fulfil these needs we extended DSpace and created DSpace-GLAM • An extension of DSpace aimed at managing Digital Cultural Heritage • Provide IIIF based add-ons for curating and exploring digital objects • Provide an extended and extensible data model to display contextual relationships at different levels and to manage different metadata schemas and conceptual models
- 32. DSpace-GLAM: built on top of DSpace 7 The current release is based on DSpace 7. It relies on the new DSpace 7 technological stack - REST API - ANGULAR UI However, DSpace-GLAM provides much more features for managing Cultural Heritage than DSpace
- 33. DSpace-GLAM DSpace-GLAM it's a solution for managing Digital Libraries The GLAM acronym highlights the power to include and manage the cultural multi- domain: ancient and modern books, fonds, museums objects, documents, video, audio, maps, …
- 34. Galleries, Libraries, Archives, Museums Materials from Museums, Archives, Libraries can be explored in an integrated way, but without losing the granularity of cataloging required by the respective domain standards. Cultural Metadata Italian and International Standards (ICCD, ICAR, ICCU, EDM, etc.) Metadata related to other domains (tourism, botany)
- 35. We developed 3 add-ons to "enrich" the IIIF experience. • Image Viewer • Document Viewer • OCR & Transcription The 3 add-ons implement several curation task for an easier digital resources management
- 36. IIIF Image Viewer related curation tasks Upload Upload images to the IIIF Image Server (photo gallery) Upload Upload images to the IIIF Image Server (digitized book) Forbid Forbid file download for files uploaded on image server Allow Allow file download for files uploaded on image server Create Create access image for RAW Types Create Create multipages PDF from IIIF Images Remove Remove all metadata bundles created by a previous upload
- 41. Modeling Structural Metadata • Structural Metadata can be uploaded in batch: • using the Simple Archive Format (as in DSpace community edition) • using an Excel file
- 42. Enhanced Batch Import Import structural metadata and images by means of xls files
- 44. The Document Viewer Explore PDF files using the IIIF Image Viewer
- 45. Document Viewer related curation tasks Extract images from PDF (CMYK) Extract images from PDF (RGB) Extract images from a scanned PDF Extract raw images inside the PDF (no OCR) Rebuild the PDF ToC
- 46. The OCR & Transcription Module Allows to extract text from images and index it
- 47. Complete OCR management • By means of its curation tasks, the module is able: • to extract OCR from images • to index the extracted text
- 48. OCR & Transcription module's curation tasks Extract Extract text (hOCR) from images Send Send OCR to the annotation server Consolidate Consolidate hOCR for the fulltext indexing
- 49. Integrating metadata and extracted text: the OCR text is indexed
- 50. Launching the Curation Tasks From the Administer section of each item you can launch the curation tasks
- 51. Extending DSpace data model Digital Object (Book, Archival Document, Picture, Museum Object, etc.) Fonds Person Event Place Path Aggregation Journal Fonds Project OrgUnit Entity Entity Entity Digital Object Annotation
- 52. The data model - Links the digital object with People, Places, Events, Fonds, ecc. - Having an overview of artistic productions, thematic and historical paths, - Define a relationships network to be explored, navigated and studied
- 71. Structuring Digital Cultural Landscapes Through DSpace-GLAM, today many institutions are enhancing the relationships among their content, shaping "their" digital cultural landscapes according to the dimensions of variability needed Digital cultural landscapes are “virtual ecosystems” in which digital cultural heritage subsets are related with entities such as people, places, events, fonds, etc., according to different visions and interpretations, in order to generate new knowledge and to open up new perspectives. Such "digital landscapes" can be visualized either as Semantic Networks, Paths or Aggregations.
- 72. The Network Lab: explore the relationships graph Based on the relationships defined at the data model level, DSpace-GLAM is able to construct graphs, thanks to the Network Lab
- 73. The Network Lab: explore the relationships graph For example you can navigate through the different Byzantine emperors who commissioned interventions on a building and explore their relationships with architects and workers who actually did the work In this way it is possible to uncover "hidden relationships" producing new knowledge
- 74. Exploringthe history of patronage related to a building("time" variablein a diachronicsense)
- 75. Exploring evidence related to the same era ("time" variable in a synchronic sense)
- 76. Exploring evidence related to the same place (contextualizing by space, "place" variable)
- 77. Explore evidence related to the same place and time (contextualizing by space and time)
- 81. Cultural Paths and storytelling
- 82. Paths Paths mainly tell "stories." In DSpace-GLAM, they have been enhanced and fully integrated into the data model Paths can also include objects of different types (Documents, Photographs, People, Events, Places, etc.). The same object can be included in different Paths
- 84. Paths creation and storytelling With DSpace-GLAM, it is easy to create paths by relating different entities, highlighting contexts, structuring exhibitions and enhancing itineraries Greater interaction between text and digital resources makes it possible to build real narratives around cultural heritage
- 85. An Historical Path: "The Flagellation"
- 89. Annotating Images: the Digital Library as an educational, study and research tool
- 90. In DSpace-GLAM each digital object and each concept (Person, Event, Place, Path, etc.) is a node in a single semantic network and IIIF is perfectly integrated in it
