## Gathering Audio Metadata for the Monterey Jazz Festival Concerts 

- OLAC 2006
- By Nancy J. Hoebelheinrich, Stanford University Libraries

## Workshop Goals

- Surface issues associated with gathering MD req’s for access & long term preservation of audio files
- Demonstrate how to use METS for content packaging &
- MODS for description & retention of logical & physical structures of digital audio objects
- PREMIS for preservation MD
- AES Draft Data Dictionary & JHove for Format MD

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Monterey Jazz Festival Project Description

- Multi-year, multi-part project initiated jointly by Stanford University Libraries and the Monterey Jazz Festival
- Goal to preserve and provide access to approximately 750 original audio and 92 original video recordings
- Recordings
- Date from 1958 to present
- Document the world's longest running jazz festival

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Project Description, cont.

- Grant funding provided by:
- Grammy Foundation
- National Historic Publications and Records Commission
- Save America’s Treasures.
- Current timeline:  October 1, 2005 – September 31, 2008.

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Collection Description

- Complete collection currently comprises over
- 1,200 sound recordings
- 370 moving image materials
- 130 linear feet of paper-based records of the founding organization
- Forms a unique collection of historic recordings of high research value, currently inaccessible to scholars due to the condition and format of the materials
- Approximately 750 tapes have been selected to be digitized
- Formats: 1⁄4” and 1⁄2” analog reel tape, audiocassette, and digital audio tape.  (only audio for this project)

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Intentions for Collection

- Creation of master and derivative digital audio files
- Augmentation of existing descriptive MD to access component level files
- Entire digital collection will be accessible to listeners on Stanford campus
- MD made accessible to the public via the SULAIR web; [selected sound clips may also be available]
- Deposit into preservation repository (SDR)

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

**Notes:**
On-site access to audio files only via use copies on CD (and possibly also MP3 files on a listening station).

## Descriptive / Structural MD Req’s per curator & SDR

- Retain relationships among “*tracks*” or segments, *tape-side* and *tape* to allow physical access to analog artifact
- Replicate physical structure, but also provide direct access to the logical structure
- “Find”, “identify” & “select” by tape, performer(s), performance, date

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Minimal MD Req’s for SDR

- Structural
- Descriptive enough for minimal access
- Admin
- Technical for Audio
- Preservation
- Rights
- MD Packaged with its resource

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## FM Pro MD @ beginning of project

- Field tags =
- Tape number
- Performer (of all on given tape) by group with individual & instrument also listed
- Performance (of all songs on the tape, differentiated by performer)
- Date of performance

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Date #1

- Date #2

- Date #3

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## The plot thickens...

- How to [retain] link between Descriptive MD and “digital-physical” files??
- Assigned “markers” = virtual BE / END determined by timestamps
- Files & structural naming conventions

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Why worry about digital object structure?

- So many files
- No inherent order to their order
- Just streams of bits

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Slide 23

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Physical structure by naming convention,  hmm....

-                 0001pm.wav                0001pm.sfk                0001pm.wav.gpk                0001pm.wav.mem                0001sh.wav                0001sh.mrk                0001sh.cd                0001sh.wav.gpk                0001sh.wav.mem

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Physical structure by file naming w/ directories

- sul-dl-nas1\mjf\Batch01\040606\        PM\                0001pm.wav                0001pm.sfk                0001pm.wav.gpk                0001pm.wav.mem        SH\                0001sh.wav                0001sh.mrk                0001sh.cd                0001sh.wav.gpk                0001sh.wav.mem

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Long term storage	bets

*Different *naming conventions
*Different *directory structures, if any
- Need for device & OS independence
- Value in “packaging” of metadata & content together even if stored separately

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## What to do?

- Packaging = 	Descriptive + Structure
- METS = (Logical structure expressed as)  Descriptive MD + (Physical Structure expressed as) Structural Map

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## How does METS work?

- Initial scope limited to objects comprised of text, image, audio & video files
- Technical Components
- Primary XML Schema
- Extension Schema
- Controlled Vocabularies
- Community based profiles

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## METS XML Schema

- METS

- Header

- Descriptive

- Metadata

- Administrative

- Metadata

- Content File

- Inventory

- Structural

- Map

- Behaviors

- METS

- Document

- Structural Link

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Structural Map is key

- Digital Object modeled as logical or physical tree structure (e.g., book with chapters with subchapters, image file with encoded text transcription file and audio file of oral interview....)
- Every node in tree can be associated with descriptive/administrative metadata and...
- Individual/multiple files (or portions thereof) or
- Other METS documents

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Associated Metadata

- Descriptive
- Endorsed XML schemas of these standards to date:  MARCXML, Dublin Core simple, MODS;  can use others such as FGDC, VRA, etc.

- Administrative
- Technical (Z39.87 for still images, Text endorsed),
- Rights, Source
-  Digital Provenance (PREMIS endorsed)

***Can be associated with entire digital object or subcomponent(s)***
***Can be multiple instances; type used is not prescribed***
***Can be contained internally (as XML or binary files)***
***Can be contained externally by reference (using Xlink)***
***Provides controlled vocabularies for tags and declaration of standards used***

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

-  Book

- Desc MD (MARC or DC or MODS)

## Slide 35

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Taking advantage of the technologies

- Mechanism for keeping tracks (segments) connected to tape-side
- using mods:relatedItem to nest, or not
- Retaining IDs from data provider – SDR
- Using subfields / attributes to trigger code events, e.g., subject/genre & title information

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Viewing the XML

*See* dmdSec
*See *fileSec
*See *structMap

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Administrative MD

- rightsMD using PREMIS Rights
- sourceMD used AES draft data dictionary elements
- techMD for format specific MD
- Preservation Master (Broadcast wave, uncompressed) (AES & Jhove)
- Service High (Broadcast wave, compressed) (AES & Jhove)

- NjH, Stanford University Libraries, 27 - 28 October, OLAC 2006

## Viewing the XML

*See* amdSec
- rightsMD
- sourcMD
- techMD
- For file
- For format
