WHAT IS METADATA?

• Standard definition: • “Metadata is data about data”



WHAT IS METADATA?

• Standard definition: • “Metadata is data about data”

• Better definition:

• Metadata is information about a thing, apart from the thing itself

• Metadata surrounds us…



REAL-LIFE EMBEDDED METADATA



MAKING “SMART” ASSETS

• What makes an asset smart?

• What makes an asset smart?• A description that tells you about the asset.• “Controlled” Keywords are used to “tag” its “aboutness”• You can easily find the creator, and copyright holder• You know how to credit the asset if published• You know what rights you have licensed (if not your own)



DOCUMENTING YOUR WORKFLOW

• Use the IPTC / CEPIC package




• How do we add this “smartness”?• By using “Standard” Metadata Schemas

• Exif• IPTC-IIM• IPTC Core• IPTC Extension• Dublin Core• PLUS• PMI (PRISM Metadata for Images)

• How do we add this “smartness”?• By using “Standard” Metadata Schemas• By embedding the metadata values with software like:

• Adobe Bridge• Adobe Creative Suite Apps (Photoshop/Illustrator/InDesign)• Photo Mechanic (Camerabits.com)• Media Pro (PhaseOne.com)• Apple Aperture• Or Other DAM Software




• “Smart” Assets are ideal for distribution:• Self-describing• Recipient can see all (or nearly all) the data you can.• All “derivative” files inherit this “smartness” as well

EMBEDDED METADATA MANIFESTO

• The Five Guiding Principles:• 1. Metadata is essential to describe, identify and track digital

media and should be applied to all media items which are exchanged as files or by other means such as data streams.

• 2. Media file formats should provide the means to embed metadata in ways that can be read and handled by different software systems.






• 2. Media file formats should provide the means to embed metadata in ways that can be read and handled by different software systems.

• 3. Metadata fields, their semantics (including labels on the user interface) and values, should not be changed across metadata formats.




• The Five Guiding Principles:• 4. Copyright management information metadata must never

be removed from the files.




• The Five Guiding Principles:• 4. Copyright management information metadata must never

be removed from the files.• 5. Other metadata should only be removed from files by

agreement with their copyright holders.

TESTING ASSETS FOR METADATA PRESERVATION

• Test by Reading One or All After Processing:• Use off the shelf DAM “Cataloging” software

• Media Pro• Idimager• Extensis Portfolio• Canto Cumulus

• Use Originating software (Photoshop / Bridge)• Use Command Line tools (ExifTool)• Use free reader tools

• Mac: Apple Preview, Spotlight, Search function in Finder• Windows: IrfanView, Exifer, etc. • AIR: EMET (Embedded Metadata Extraction Tool)




• ALWAYS! Test After Moving or Posting Online

WHAT KIND OF ASSETS CAN WE MAKE “SMART”

• Image Files• JPEG• TIFF• PSD• EPS• DNG

• Document / Illustration Files• PDF• Adobe Illustrator (AI)• Adobe InDesign (INDD)• EPS




• Audio Files*• XMP or ID3 metadata tags?• mp3, aiff,aif, wav, m4p, m4a, snd

• Video Files*• XMP or QuickTime wrapper?• mov, mpg, mp4, divx, qtz, avi, wmv, dv

*These file formats have decreased interoperability



WHAT DO YOU ADD TO MAKE AN ASSET “SMART”?

Use the “Guide To Photo Metadata Fields”

http://photometadata.org/META-Resources-Field-Guide-to-Metadata


http://photometadata.org/META-Resources-Field-Guide-to-Metadata


WHAT DO YOU ADD TO MAKE AN ASSET “SMART”?

Use the “IPTC / CEPIC Image Metadata Handbook

QUICK REVIEW: UPSIDES

• Advantages to Embedded Metadata?• Metadata makes it easy to find/locate assets in collections• Find the File >> Find the Info• Metadata travels with any “derivative” files you distribute.• Can be “leveraged” in downstream uses.



CONNECTING THE DOTS: REVIEW

• Advantages to Embedded Metadata?• Metadata makes it easy to find/locate assets in collections• Find the File >> Find the Info• Metadata travels with any “derivative” files you distribute.• Can be “leveraged” in downstream uses.



QUICK REVIEW: DOWNSIDES

• What are the Downsides to embedding metadata?• Not all applications “know” to use this info• Some applications may inadvertently remove some/all info• Increased time to update info in large files (photos or videos)



HOW DO I FIND OR CREATE METADATA / TAGS?

• Tips to create “Smart” Collections• Add metadata before placing assets into database• Make adding metadata part of a documented workflow• Require users to annotate and tag assets they contribute• “Batch” the addition of metadata whenever possible• Use a “controlled vocabulary” when adding keywords



HOW DO I FIND OR CREATE METADATA / TAGS?

• How do you want to “Tag” your Assets?• Manually: In-house• Manually:

• Request to Suppliers• Out-source to Third Party

• Auto-magically
