Fixity	To ensure that an object is unchanged from its accepted state	Redundancy, error-corrrecting codes, message digests
Authenticity	To ensure that an object is what it purports to be	Provenance, cryptographically-secure signatures
Ontology	To understand an object’s significant nature	Syntactic, semantic, and pragmatic characterization
Visibility	To enable users to find objects of interest	Public discovery systems and registries, exposure for web harverst
Utility	To expose an object’s underlying content	Behaviour-rich delivery
Portability	To facilitate content sharing and succession planning	Self-contained, self-documenting objects, packaging standards
Appraisement	To understand the consequences of time	Analysis and assessment
Timelines	To know when a preservation value is threatened	Technology watch, stakeholder engagement

Scary

With Ben leaving our team some scary thoughts already passed in my head…

What if I do something that brakes his work?
What if, despite my study, I cannot do some simple basic tasks?
What if…

Staying so long away from work, and even longer from coding (remember that is not only maternity leave, there are months of only webdesign and no programming) creates an insecurity that I never felt before. Nevertheless, I’m clever enough and I think if I just focus on the material to be digested and examples left I will manage not only the mundane tasks but to evolve and improve the system.

Today I start with my first task of lifting an embargo from ONE item in ORA. Let’s see how it goes.

Wish me luck! 🙂
