Introduction
Types of Multidimensional Media
Digital Images are organized using pixels, the smallest elements of an image, which are arranged across 2 dimensions (x and y axis).
Image resolution refers to the number of pixels, and it is usually given in 2 dimensions (e.g., 800 × 600 pixels).
Digital Video is a 2-dimensional or even 3-dimensional type of media.
Videos consist of multiple frames stored in 2 dimensions (like images).
Videos also have a resolution and frame rate (Frames Per Second).
3D Images or Models are files containing vector data describing spatial information.
Rasterization is the process of converting vector graphics into raster images.
Various aspects need to be considered when collecting, storing, and managing multimedia files effectively.
Recording metadata and using appropriate file naming conventions is important.
Uniform Resource Locators (URLs)
- URLs can be a simple means to find a website.
- URLs can also include additional information which allows a server to change how the webpage is ‘served’.
- Anchors allow to easily jump to part of the page.
- URLs also provide the means to use a website as a database which can be queried via the URL path.
Making it FAIR
| Principle | Key Points |
|---|---|
| Findability | - Available metadata - Allow for searchability - Persistent IDs |
| Accesibility | - Use web protocols for access - Allow for authorisation - Digital inclusion/exclusion |
| Interoperability | - Data integration - Overcomes data silos - IIIF for visual media |
| Reuse | - License content - Avoid data becoming lost |
Virtual Research Environment
Multidimensional media requires good management, to underpin collaboration and open access/science processes.
Virtual Research Environments (VREs) are collaborative spaces for data-driven research.
VREs offer workspaces for secure data storage, mailing systems, forums, and data analytics capabilities.
