Configuring a collectionConfiguring a collection

What’s a Collection?

A group of objects (items) that

• Share the same metadata schema

• Live on the same CONTENTdm server

How many Collections can I have?

• Up to 200 collections per server

How many items can be in a collection?• 16 million items per collection

Populating a collectionPopulating a collection

Through the use of a “Project”

What’s a CONTENTdm Project?

A workspace on your personal computer

• Into which you import up to 5000 items at a time

• Where items reside until you upload to the server

A group of settings that are applied to the items

• E.g., image display resolution, file format, branding

• E.g., automatic metadata input

How many Projects can I have at one time?

Limited only by your disk space on the workstation

What’s a CONTENTdm object or item?What’s a CONTENTdm object or item?

CONTENTdm can store/index/search items in various formats

Display any file format:• Viewed with a Web browser natively or viewed via

a plug-in

• Including: JPEG, JPEG2000, TIFF, PDF, WAV or MP3 audio, AVI or MPEG video, html, MrSID®

Simple items—e.g., images, sound files, research papers (We’ll load papers today as PDF items.)

Compound objects—multiple simple items assembled together

CONTENTdm Compound ObjectsCONTENTdm Compound Objects

CONTENTdm defined classes

• Documents

• We will load a section of a yearbook

• Postcards

• We will load a handwritten postcard with a typescript

• Monographs (Structured documents)

• We will load a book with chapters

• Picture Cube (six-sided views)

Dublin Core metadata element setDublin Core metadata element set

Review: Basics of CONTENTdmReview: Basics of CONTENTdm

Simple and Qualified Dublin Core element sets offered

• 100 fields per collection

• Only DC.Title required to create a record

• Dublin Core is basis for cross-collection searching

Text is stored in a metadata field

• 128,000 characters per “full text search” field

200 collections/server—i.e., 200 different metadata schema

Providing searchable textProviding searchable text

Remember: metadata fields can be made searchable

In addition, full-text, extracted from the digital object itself can be stored in a metadata field designated as “Full text search” data type, in any of three ways:

1. Extracted (by server) from PDFs (if embedded to begin with)

2. Imported as .txt transcript

• Typescripted from handwritten

or

• OCR’d in advance (external OCR engine)

3. Generated by OCR “on-the-fly” (integrated ABBYY FineReader®)

Reformatted materials e.g., books, documents, posters, broadsides, memos—scans may all contain text

Born digital files e.g., PDFs, single or multi-page

• Single-page PDFs viewed as items

• May opt for ‘in-line’ Adobe viewer

• Multi-page PDFs may be handled as if compound object of type “document”

• Server side conversion

• Import as simple item regardless of conversion choice

First things First-- Recap: Prepare the CollectionFirst things First-- Recap: Prepare the Collection

For importing searchable text items, whether singly or in batch—at minimum:

1. One empty, searchable field is configured as “Full text search” data type to hold text

2. Collection is configured to treat PDFs as compound objects.

3. Collection is configured to provide Full Resolution file management.

4. Other fields are made searchable, hidden, moved, or added, as needed.

5. OPTIONAL: the Web templates are adjusted to suppress display of components of compound objects in search results.

Recap: Prepare the itemsRecap: Prepare the items

These PDFs have been created with searchable text embedded.

Beware: Not all PDFs are created equal!

A batch of simple items, two ways:

Method A: Import a batch of simple digital items stored in folders

(where Template Creator only is used to automatically generate metadata)

Method B: Import a tab-delimited text file naming and describing the digital items

(where metadata also resides in imported tab-d file)

Recap: Behind the scenes: prepare the items, organize folders

Recap: Behind the scenes: prepare the items, organize folders

Method A:

PDFs had been created with text (Adobe, Word conversion)

For importing a batch of PDFs in one load,

• All PDFs were stored in one folder.

• Digitization Training

Method B:

• All PDFs were stored in one folder.

For loading with tab-d files:

• Prepare .txt file of metadata

• Place it in a directory different from the .pdf files
