# CHAPTER 2

Goal #1: Signposting

Add Signposting Link headers to HTTP or HTML of existing repositories

 

Improve Signposting tooling

Lessons learnt #1

Start with the easy

Signposting to your own custom JSON is better than no links at all.

Allow gradual growth to an FDO.

1.

2.

Identify the profile

Linking to an OpenAPI specification is much more powerful than just application/json.

Allow gradual building of an FDO profile.

3.

Annotate existing PIDs

Third-party services are free to express additional data about an official PID.

How to inform upstream about additional annotations?

# PRESENTING CODE

Lessons learnt #2

FDO RO-Crate scope

Decide on an crate size that fits available data/metadata and can have a resolvable identifier.

1.

2.

Digital twins are not datasets

For non-digital resources, the metadata needs separate PID so both can be described in the crate.

Use Detached Crate referencing only absolute URIs/PIDs.

3.

Prototyping

Allow FDO to be prototyped before the model is settled.

Simpler architectures (e.g. GitHub Pages) accelerates prototyping but have less flexibility.

# CHAPTER 2
# CHAPTER 2

Goal #3: FDO

Can we do hybrid deployment of FDOs with a Signposting/RO-Crate overlay?

 

Augment a portal that is built on Cordra

the PID of which the FDO record is part, in DiSSCo this is a Handle or DOI. It is recommended to store this pid also in the local collection management system for the specimen.

structuralType

Nature of the digital object, compatible with DOI schema requirements. The nature of a digital specimen object is always "digital". Other digital objects (outside DiSSCo) could be of physical, performance or abstraction nature.

pidStatus

A PID is considered to have a lifecycle, PID status indicates the status in the life cycle, e.g. draft, active, retired. PID statuses are described further in the PID infrastructure design. One of: one of: DRAFT, ACTIVE, RETIRED, OBSOLETE, FAILED, MERGED, SPLIT

referentType

A generic name for the type of object that the DOI refers to. This is different from digitalObjectType that points to a specific type, e.g. there can be different types of digital specimens that each have a slightly different metadata schema because they describe a different kind of specimen, like a botanical versus a geological specimen.

primaryReferentType

The primary type of the referent in the DOI Kernel XML Schema (e.g. creation, party, event). This is an open list. For digital specimens and media it will always be creation.

  1. Examples are using test prefixes
  2. Profile handles don't have a profile nor type
  3. Index seems to have meaning?
  4. Mixes general and specific
  5. +1 Use of full URIs
  6. +1 type AND profile

Handling handle

  • Requesting EOSC B2Handle service is very slow
    • Was not assigned "real" prefixes -- common issue
  • B2Handle (test) server unreliable:
    • SSL errors
    • Could not update PIDs
  • Unclear how to indicate profile in handle
  • Unclear how much of the FDO metadata should be duplicated into the Handle
  • Unclear which keys to use in Handle
  • Unclear if index in Handle matters (FDO profile is index 1?)

Profile profile needed

Still too unclear how to express a profile. JSON Schema kind-a works but is rudimentary.

RO-Crate specify (sub)profile inside -- do we duplicate that in its Handle?

3.

Granularity varies

The FDOs may be fine-grained (e.g. to support their operations)

An RO-Crate should make sense on its own -- augment with metadata from compound FDOs.
