Identifiers

• K. Richards, R. White, N.

Nicolson, R. Pyle, (2011)

“An identifier is a unique identification code that is applied to 'something', so that the 'something' can be unambiguously referenced.“

Identifiers

• unique
• stable / persistent
• citable online & offline
• (somehow) resolvable

“An identifier is a unique identification code that is applied to 'something', so that the 'something' can be unambiguously referenced.“

Strategy

• Choice of IDs is strategic question

Anyway, we want to present our data online! So we will use web-based systems / services!

Advantages of URIs

• URI = Uniform Resource Identifier
• globally unique through controlled web domain
• dereferenced via standard web protocol HTTP

– content (type) negotiation – standard software and services

• easy to use for users and maintainers

– intuitively ready for use (users) – dereferencing is easy to configure (admins)

• cheap
• semantic web / linked data
• high probability of being sustainable over decades

CETAF ISTC

• aims to implement a consistent identifier

system i.e. collections held by CETAF institutions

• based on http-URIs
• create endpoints querying lists /

catalogues of all URIs

Stable URIs

A generally recommended URI pattern:

http://subdomain.yourdomain.org/path/variable-id

Example: http://coll.mfn-berlin.de/u/ZMB_XYZ_123456

Stable URIs

http://subdomain.yourdomain.org/path/variable-id

• subdomain, because your web-domain is used for
• ther content, too
• yourdomain.org should be owned and fully

controlled by you

• path as a kind of “name-space”, because it's easier

to redirect and is extensible for identifying other groups of resources

• variable-id is your internal identifier (inventory

number, UUID, etc.) and has to be locally unique

Stable URIs

• Keep the pattern simple from the start, but

flexible

• Clean URIs instead of long GET-parameters

http://coll.mfn-berlin.de/identifier.php?namespace=unit& inventory_number=ZMB_XYZ_1213456&redirect=1&collectio n=insecta http://coll.mfn-berlin.de/u/ZMB_123456

Quick Response (QR)

http://coll.mfn-berlin.de/u/ZMB_Phasm_D038

Quick Response (QR)

• QR codes => binary information
• Machine readable

– easily to include in digitization workflows – save time / avoid typos etc.

Quick Response (QR)

• Binary „interface“ between physical
• bject and digital representation

Use cases for mass digitization

Use cases for mass digitization

Level 1 Containers Level 2 Species Level 3 Specimen

i.e. Type specimens

(1) Collection management

• Collections change

– Track changes in your database just by scanning QR codes – URI redirects to edit form in the intranet

(1) Collection management

• Shopping carts for collection objects

for batch workflows

Generic tool for forms

• Using customized forms in the free

mobile application ODK Collect

(www.opendatakit.org)

• Trying to enhance

– data capture – connection between physical object and digital representation in workflows

databases

templates

ODK form data

Batch process

Examples:

• changes in location
• loans
• cataloging
• demands for digital data

(2) Digitization starts in the field

(3) Image analyses

i.e. for validation, segmentatation etc.

Conclusions related to DINA

DINA efforts are a chance to ...

• … better combine workflows in managing

both, collections and their digital representations

• … better interconnect collections
• … join efforts in developing web-based

components

• … jointly implement (new) standards in

collections

Thanks for your attention!
