Basic Authoring Needs

Search/browse repository for documents Identify resources (docs/subdocs/mashups) of

interest; place them in a “workspace” Create new works (mashups) from pre-existing

documents or subdocuments and original material

Store new works (mashups) in repository in appropriate format: .PPT, .DOC, .HTM, ...(Keep track of the subdocuments & how/where they were used.)

Features

With subdocuments in the repository, we can:

• Automatically generate citation lists

• Explain where information came from:

• Show bibliographic details of sources

• Show subdocuments in original context

Explain how information is used by others: “Have I (or anyone else) used this question

in an exam before?” Note: subdocuments can overlap; we need

recursive processing.

Make this easy to use Use familiar tools to create mashups

Use copy-and-paste or other mashup-creation mechanisms

Don’t introduce unnecessary additional mouse clicks

For one Subdocument“Where did this come fromand where else did it go?”

Current ImplementationWe have “assembly language” for our vision:

• subdocument selection using Copy

– In MSWord, OpenOffice Writer; creates 3 streams for Fedora (FOXML, text, subdoc)

• subdocument ingestion to Fedora including relationship creation

• Fedora search showing parent/child

• Note: we are using existing Fedora relationships IsPartOf, HasPart (we need subdocument-specific relationships for final implementation)

• No mashup creation (yet)

Selection using digital pens

Summer project for a high school intern (Kelson Luc)

Worked with the Anoto digital pens – with a digital camera near the tip of the pen and special paper with a dot pattern.

Print a pdf file on the dotted paper.

Circle the selected text with the pen.

Write a comment – in the margin – with the pen.

We are lacking software from the pen manufacturer to put the whole system together.

Subdocument: .doc file

Subdocument: text file

I wish I had never concealed it. For I, and I only, know what manner of fear lurked on that spectral and desolate mountain. In a small motor-car we covered the miles of primeval forest and hill until the wooded ascent checked it. The country bore an aspect more than usually sinister as we viewed it by night and without the accustomed crowds of investigators, so that we were often tempted to use the acetylene headlight despite the attention it might attract. It was not a wholesome landscape after dark, and I believe I would have noticed its morbidity even had I been ignorant of the terror that stalked there.

Searches With Relationships

Discussion

• Will Ensemble users want to download/use our plug-ins, e.g., for MS Word?

• Which “mashup” creation tool should we provide?

• Where should subdocuments be stored?

• (Metadata records for) subdocuments and their parent documents and their mashups needs to be in the same repository.

• We could extend the browse/search interface for Ensemble to be subdocument-aware.

An Idea for the November launch

Develop an example – with documents from Ensemble that are used to create one or more mashup documents. (This will induce some number of subdocuments … with their relationships.)

Use it to demonstrate how the rewards could track use of materials across mashups.

Let people browse and search the example.
