Agenda

1. Islandora 8 Special Topics Call: Core Islandora 8 Concept of an Object. Questions to pose?
2. From last week's call: "come with topics we want to discuss in a larger community meeting about what to expect from Islandora." The group agreed that we need to put some thoughts together on data modelling, so we can then get feedback from the wider Islandora community.
   1. One big question is what is the relationship between a resource node (which describes the work or thing) and the files that contain the content of the work or thing.
      • Currently, one resource node is associated with zero or more media. In Drupal terms, a media (or to follow the Latin, a medium 😸) encapsulates metadata about a single file. An important piece of metadata for each file is how the file is intended to be used, which is expressed using the "Media Use" vocabulary. Terms from this vocabulary include "Original file", "Thumbnail", and "Extracted text". So the model so far is: a resource node may have multiple media, but each media describes a single file, e.g. a single Original file.
      • This model poses a head scratcher: what if the content the resource node describes is not a single file, but is multiple files? For example, a video that is actually 3 separate .mp4 files. In the current Islandora data model, we can upload all three .mp4 files and tag them as "Original file", but Islandora assumes that there is only one original file media per resource node.
      • Another assumption Islandora currently makes is that if we want to associate all three .mp4 files with the resource node that describes them, we create a resource node for each file (along with the corresponding media and file entities) and then associate each of those resource nodes with the first one as children. So now we have 4 resource nodes (the first one plus one for each part of the video it describes) plus one media for each of the parts.
      • Some issues we need to discuss coming out of these assumptions include what is the UX for creating objects that have multiple files; how do we manage technical metadata (e.g. FITS) for each file; how does searching/browsing work for objects that have multiple files.
