Meeting Notes

Work Summary:

1. Restructured and finalized file organization to enable easy access control:
--masters audio files:
/home/soul/public_html/handel/multimedia/audio/aiff/lpxxxx/*.aiff
--mastesr image files:
/home/soul/public_html/handel/multimedia/image/tiff/lpxxxx/*.tif
--derivatives: /home/soul/public_html/handel/multimedia/lpxxxx/
[noncopyrighted][copyrighted]/[audio][image][text]/ ...

2. Read up on dating LP: http://cctr.umkc.edu/~wsistrunk/poster.htm
Useful points:
Use knkowledge of album cover at and historicla styles to approximate the date of release of an album:
--Early LPs (~1948-1955): fewer colors; minimal cover art; reproduced line-drawing; cardboard was the norm.
--Later 1950s: some color phonograph but not "natural" looking
--1967 onward: digital artwork; eye-catching packaging; double sleeves common
Physical description:
--Early LPS (~1948-1955): heavier with a feel of the old 78 rpm shellac recordings
--~1956 onward in favor of 12-inch format while the 10-in LP fades
--~1968 stero became the preferred and nealry exclusieve standard; after 1968 most of the major labels wer no longer issuing new LPs in mono.
Others:
--The words "Long Play" or "LP" tend to be featured very prominently on many recordings form the 1950's to differentiate from the 78 rpms
--advertisement can give genereal dates
--"digitally remasterd" indicates from around the 1070's and early 1980s
--price guide or receipt
--copyright dates
--chart of matrix number with corresponding dates of release (if available at all)

Other references to look (may or may not be useful):

3. Digitization time calculation for a typical LP album in English with one audio disc
Approximation: 2 hours 30 minutes (not including breaks)

Detail:
A. Scanning one image @1200dpi 24bit: ~13 min
Cropping image: ~2 min
Saving one image @1200dpi 24bit: ~12 min
Subtotal: 27 min
B. Cleanning one side of audio disc: ~5 min
C. Digitizing one side of audio: ~25 min (only 23 minutes of audio on one side max)
D. Type one side of track information: ~10 min
E. Entering metadata front cover: ~5 min
F. Entering metadata and type text (on back cover or inserts): ~1 hour (one column of text ~667 words ~20 min)

Depending on the workflow (i.e interleaving of multiple tasks), time is both estimated to be 2 hours and 30 minutes.

Workflow scenario 1: clean audio disc side 1 -> audio capture audio disc side 1 -> enter metadata front cover -> enter metadata back cover -> type content notes [clean audio disc 2][capture audio disc 2] ->scan audio disc 1 -> scan audio disc 2 -> crop image -> scan front cover [type track information audio side 1] [type track information audio side 2] -> scan back cover (can start cleaning and capture another album here..)

Workflow scenario 2: scan front cover [type track info audio side 1][type track info audio side 2] [clean audio side 1] -> capture audio side 1 [enter front cover metadata][enter back cover metadata] -> clean audi0 side 2 -> capture audio side 2 -> type content notes [scan audio side 1][scan audio side 2] ->scan back cover

Pending Tasks:
1. Modification to the data entry form. Propose to:
--provide reapeatability to certain fields such as admin notes
--incorporate default inheritance feature (to avoid typing or copy paste time)
--add track metadata entry points for section/movement below a main song title (facilitate better track separation)
--content notes be stored in db as opposed to external document (hard to be incorporated for full-text search)
Other considerations:
--some kind of tagging for text blocks (e.g. paragraphs of program notes or lists of other musical work reference ), using e.g. TEI syntx for better presentation and structure purposed

2. Continue to check re-release of LPs (gone through 15 out of 147)
--been done using the OCLC worldcat
--make note of how many copies owned in the world to help make digitization selection decision
--on worldcat using keyword search using performer names and title usually work well

3. Update MAPP and compile bibliography
