Infrastructure for AV-data

It’s there, but will it be used?

The establishing of a sustainable infrastructure for tools and data for the humanities (and SS)

What is an infrastructure?

• Infrastructure is a basic physical and organizational structure needed for the operation of a (scientific) organisation.

• It can be generally defined as the set of interconnected structural elements that provide framework supporting an entire structure of development.

• It is an important term for judging scientific organisation’s development.

INFRASTRUCTURE FOR AV

AV-material

More and more AV becomes available2013: 72 hour/min on YouTube

• Digitization and Preservation of existing material• Easy and cheap to produce• Easy and cheap to store (YouTube, Cloud)• More professional productions• Extreme need for self-expression?• It’s there because it can

There is no data like more data

What do we do with all this dataDo we need to setup criteria for selection?Do we need a special infrastructure for AV?

Infrastructure for AV-material

• There are AV-infrastructures but

– They are often primitive

– Not interoperabel

• But will it be used?

PROBLEMS SEEN IN THE LAST YEARS

Doing an assessment to set a baseline (2010)

Telling the story on conferences and meetings

ACCESSIBILITY

How to find the right material?

• AV-archives are not connected

• Finding needs metadata witch is lacking

• Not all archives want their (meta)data to be open for everyone

• Large part of the metadata may be restricted and/or not accessible

• Searching capability is limited (no semantic search or ontologies)

Problems with access

• (Federated) login is not always the case

• Source data is mostly not accessible

– Restriction

– Technological problem (no streaming)

linking a person's electronic identity and attributes, stored across multiple distinct identity management systems,Ideally resulting in a onetime login

Not enough context

• The metadata is often created with the purpose of the original recordings in mind.As a result much necessary context information is missed

• Data without the necessary context for my research(are they family, why was it recorded, where was the material used before)

• It is difficult (not technical but organisational) to add new metadata to existing collections

Not digitized

• Not all material is, or will be digitized

• Especially in big archives there is too much material and digitizing and digital storage is to costly

Virtual Research Environment

• Scholars need an environment for their work

• If possible it will be in the web with access from everywhere, a login, a storage, and an option of sharing.

ELABORATION

Traditional: make your own data

• There is still a tradition to make your own data

• In order to interchange the metadata standards are necessary

• CMDI (or any other official MD standard) is often to complicated to use without additional training -> Spreadsheet Science.

Opinion storing

• Hard metadata <-> Soft metadata

• Soft MD

– Opinions (more than one)

– Need to be added in a sustainable way

MENTALITY

Sharing

• People do not want to share THEIR data.

• This is a bigger problem wit AV-material than with text-data?

• Not used to look for existing data (attitude)

• Much more privacy issues than in text-only

SOLUTIONS

Go out and:

• Ask

• Demonstrate

• Organize workshops

• Make demo’s and prototypes

User involvement (technicians)

User involvement (scholars)

Oral History

Art HistoryNarrative psychology

Facial expression

Psychotrauma

Medical antropology

How-To material

• Make manuals and screen casts (how-to)

Co-develop

• Organize workshops where scholars and technicians co-develop.

Trigger scholars to participate

Dissemination

• We created 9 videos to show other scholars the wonderful things a good infrastructure can do

Technical

• Technology must WORK (and not most of the times)

• Technology must be understandable as much as possible

Standards

• CMDI, TEI

• Distributed metadata, so different files of metadata can be used.

CONCLUSION

AV-infrastructure

• The do exist but….

• We need to invest into a dialogue between ICT & Humanities: what do you need?

• We need to invest in the use of standards
