Another descriptor named formatIdentifier is used to reference or identify a particular rendition/instantiation of a media item.

Best practice is to identify the resource by means of a string or number corresponding to an established or formal identification system generated within an international standard or as a local identification scheme. If using a digital asset management system, media asset management system, or content management system, the identfier is often automatically assigned by the system once an entry or record is created. The key is that the identifier always be unique. PBcore recommends the use of the companion descriptor, identifierSource, to indicate who assigned a particular identification number or designation. Thus PBCore provides not only a locator number, but also indicates an agency or institution who assigned it.

• Smith, Jedidiah
• Minnesota Public Radio
• KUED-TV
• Wisconsin Public Television. Extension Division
• Central Intelligence Agency
• State of Utah. Film Commission
• University of Utah. Department of Communication
• Prostate Cancer Awareness Project
• White Mountain Films
• Simpson, Lisa, Ph.D.
• More Metadata Examples

The descriptor identifierSource is used in combination with the unambiguous reference or identifier for a media item found in the descriptor identifier. Thus PBCore provides not only a locator number, but also an agency or institution who assigned it. Both exist at the top level for a PBCore description and its associated description document (XML).

Another element named formatIdentfierSource is used in combination with the element formatIdentifier to reference or identify a particular rendition/instantiation for a media item.

Use an authority file to determine how to properly enter names and organizations. In general, PBCore recommends the following rules:

FOR PERSONAL NAMES: Enter personal names in inverted form using commas as indicated here:

• LastName, FirstName MiddleName, Suffix.
• Substitute a MiddleInitial for a MiddleName as appropriate, or ignore if not available.
• The suffix is any type of academic credential (Ph.D., Ed.D.) or familial lineage (Smithee, Alan, III)

FOR CORPORATE OR ORGANIZATIONAL NAMES: Enter corporate names in full direct form.

• Use the most specific and commonly used official name for an organization if it is distinctive enough to identify the group.
• If a particular subdivision of an organization is intended, identify both the more encompassing group as well as the subdivisions.
  • The hierarchy (main group and subdivision) starts with the main group, followed by , then the subdivision.
  • For example:
    • State of Utah. Film Commission
    • Smithee Productions. Educational Division
    • Wisconsin Public Television. Extension Division

ADDITIONAL NOTES:
For a very enlightening discussion on the complexities of entering and displaying names, see "Representing People's Names in Dublin Core.

PBCore encourages producers, stations, and catalogers to assign titles to items by using more of a natural language grammar (English language) that is understandable in what is often called a "human readable form" (as opposed to "machine readable"). PBCore recommends that you:

• Assign a title that is distinctive, authoritative, descriptive, accurate, and consistent.
• Don't use leading articles, e.g., A, An, The. Place leading articles at the end of a title using the convention of a comma followed by a space and then the leading article.
• Use upper and lower case.
• Use punctuation as needed.

Titles are typically "proper" or "given" titles supplied by the original creator of a media item. However, there are situations in which no proper or given title is available, e.g., photographs or segments harvested from a longer work or program. In these situations a "supplied title" must be invented and used to name the media item. In creating a "supplied title," be considerate of and sensitive to the end user who is attempting to search for your media item. After all, you do want others to successfully discovery and retrieve information about your media item. Don't be vague or nondescript.

Because a title for an item may be associated with or related to a series, an episode, an excerpted segment, or even an alternative title in a different language, use the companion descriptor titleType to indicate the type of title you are assigning to a media item.

• Project
• Series
• Program
• Episode
• Segment
• Alternative
• Pledge Version
• More Metadata Examples

Select from a PBCore aggregated picklist of recommended vocabulary terms.

Because a title for a media item may be associated with or related to a series, an episode, an excerpted segment, or even an alternative title in a different language, use the descriptor titleType to indicate the type of title you are assigning to a media item. 

• Where the original item is in a foreign language and a translated version is easier to search
• To spell out numbers appearing in the first five words of a title
• To express a shorter title where the original, proper title includes an author or creator's name
• For commonly used titles which differ from the official, proper title

Specific examples of Alternative Titles include:

• Utah Geography
  [where the proper TITLE is actually "The Geography of Utah")
• The Geography of Utah. Program 16
  [where the proper TITLE is actually "National Parks in the State of Utah"]
• Twelve Monkeys
  [where the proper TITLE is actually "12 Monkeys"]
• The Boat
  [where the original, proper German film TITLE is "Das Boot"]
• Farnsworth
  [where the original TITLE is "American Experience. Big Dream, Small Screen"]
• Dark Sun
  [where the original TITLE is "American Experience. Race for the Superbomb"]
• Ascent of Man
  [where the original TITLE is "Jacob Bronowski's Ascent of Man"]

• National Parks. Natural Bridges. Delicate Arch. Arches National Park. Grand County. Utah.
• Afro-American artists - Boston - Massachusetts
• Afro-American authors
• United States - Relations - Cuba
• United States - History
• More Metadata Examples

PBCore does not dictate a single subject authority or classification scheme from which to select keywords, topics, and terms. However, if subjects are assigned to a media item and the terms used are derived from a specific authority or classification scheme, use the companion descriptor subjectAuthorityUsed to identify whose vocabularies and terms are being used.

PBS PODS: PROGRAM OFFER DATA SERVICE
METADATA DICTIONARY SUBJECT TERMS...
PBCore can recommend the use of the PBS TOPIC KEYWORD TABLE used in the Public Broadcasting Service's Program Offer Data Service: PODS. The PBS staff developed the Topic Keyword List in the late 1980s to support the Program Database (PDB), a system for managing production, content, rights and funding metadata about PBS programs. The list was compiled using a variety of internal sources, most notably a glossary used to code PBS programs with public interest categories for the production of FCC ascertainment reports sent to public television stations. This rich list has been updated regularly over the years to reflect new content areas and is maintained using the Broadview traffic and program management system, which replaced the PDB in April, 2006 at PBS.

ID3 PSD...
In the realm of the radio medium, the PRI PSD Consortium (Public Radio International's Program Service Data) has released its "Recommended Field Descriptions for Program Service Data" in public radio programming. The tags are based on ID3 which is a very popular audio file data tagging format in active use by software and hardware developers around the world. ID3 tags are supported in software such as iTunes, Windows Media Player (with Microsoft proprietary modifications), WinAmp, YME, MusicMatch and hardware players like the iPod, Creative Zen, Toshiba Gigabeat and Sony Walkman. In HD radio, the PSD information is embedded in transmitted audio files and can be displayed on radios with text screens. Artist names, Song title, Year, and Genre are common tags. The ID3 Genre tag contains a comprehensive list of terms used to describe music types and can be used as a source of vocabulary when describing the subject of music media items. The numbers associated with the genre tags are the actual numeric codes carried in the ID3 data stream that are then decoded into human-readable form.
http://www.mpx.cz/mp3manager/tags.htm

NAMES...
If the subject is a person's name or the name of an organization or company, PBCore recommends using the form, structure, and grammar found in the AACR2 Cataloging Rules (Anglo-American Cataloging Rules, 2nd edition) for names.
http://www.aacr2.org/

FOR PERSONAL NAMES: Enter personal names in inverted form using commas as indicated here:

• LastName, FirstName MiddleName, Suffix.
• Substitute a MiddleInitial for a MiddleName as appropriate, or ignore if not available.
• The suffix is any type of academic credential (Ph.D., Ed.D.) or familial lineage (Smithee, Alan, III)

FOR CORPORATE OR ORGANIZATIONAL NAMES: Enter corporate names in full direct form.

• Use the most specific and commonly used official name for an organization if it is distinctive enough to identify the group.
• If a particular subdivision of an organization is intended , identify both the more encompassing group as well as the subdivisions.
  • The hierarchy (main group and subdivision) starts with the main group, followed by <period space>, then the subdivision.
  • For example:
    • State of Utah. Film Commission
    • Smithee Productions. Educational Division
    • Wisconsin Public Television. Extension Division

ADDITIONAL NOTES:
For a very enlightening discussion on the complexities of entering and displaying names, see "Representing People's Names in Dublin Core."

If you are entering free-form text descriptions for a media item, don't use the descriptor subject for this purpose. Instead, use another PBCore element called description.

If you have the interest or expertise to exploit third party subject authorities (such as PBS PODS and PRI ID3 PDS), below are listed a small sample of different subject authorities that may be appropriate for study and use.

Zion National Park, Bryce National Park, Capitol Reef, Canyonlands, Arches National Park, Flaming Gorge National Recreation Area, Dinosaur National Monument, and the Glen Canyon National Recreation Area are all visited. The controversy of land use and environmental preservation is considered in interviews with San Juan County Commissioner Cal Black and Benjamin Zerbey of the National Park Service. Rainbow Bridge National Monument and Canyonlands National Park are only two examples of the land use debate.
• The Museum Without Walls Billboard Art Project was first conceived by Professor Roger Des Rosiers, Chairman of the Department of Art at the University of Utah in the early 1970s. The idea was to invite twenty-one Utah Artists to participate in the exhibition of their works on existing outdoor billboards in the Salt Lake Valley. Called "Museum Without Walls" by Lukman Glasgow, Project Director, he stated that "such works of art in an outdoor setting must compete with the whole environment." Further, "It was an experiment with public art works designed to be understood by a much broader and more general art audience than is normal to the museum or gallery environment. Such a project then should be seen, hopefully, as a beginning and not simply an isolated event. Too long have the works of contemporary artists been regarded as a set of experiences for the eyes of only small or even elitist groups. Therefore, 'public art,' because it properly speaks to a majority in our society, is perhaps the most vital art movement occurring today."

• More Metadata Examples

Use natural language to enter descriptions. Specialized descriptions, such as rundowns and edit decision lists, should conform to the standards used by your industry or community.

Use the metadata element description for general notes, abstracts, or summaries about a media item, including text and words that are not found in the more highly structured and authority controlled descriptor subject. Use description for general purposes.

The information may be in the form of a paragraph giving an individual program description, anecdotal interpretations, or brief content reviews. The description may also consist of outlines, lists, bullet points, rundowns, edit decision lists, indexes, tables of content, or even content flags for questionable material or language. Specialized descriptions, such as rundowns, segment sequencing, and edit decision lists, should conform to any standards used by your industry or community.

If the description is a highly complicated index or a lengthy transcript, it is best not to insert so much text into a database field. Instead, generate a separate, stand-alone document. If the stand-alone document has exactly the same "intellectual content" descriptions as the seminal media item, then the stand-alone document could be entered as a separate rendition of the original where the pbcoreInstantiation container is repeated. For example, a video program and its companion transcript have the same intellectual descriptions and could be catalogued as a single metadata record, with two instantiations/formats.

Under other circumstances, where the "intellectual content" is different for two associated media items, use the pbcoreRelation container and its metadata elements to establish the relationship between the two linked assets and their separate metadata records.

• More Metadata Examples

Select from a PBCore picklist of recommended vocabulary terms.

The element descriptionType contains identifiers or flags to indicate what type of information is entered in the companion metadata field description. Below is a brief explanation of each of the terms used in the recommended picklist. Although some have very similar meanings, different terms are included to appeal to practices in different industries and organizations.

"Abstract"
If you are earmarking a description as an "Abstract," then the narrative entered in the metadata element description contains a narrative review, an individual program description, or some other summary indication of the program's content.

"Package"
If you are earmarking a description as a "Package," then the narrative entered in the metadata element description is relative to an entire array of media items, ancillary materials, promotional materials, previews, or educational materials that are bound together into a single packaged offering.

"Project"
If you are earmarking a description as a "Project," then the narrative entered in the metadata element description is relative to the combined resources specific to a defined project or initiative.

"Collection"
If you are earmarking a description as a "Collection," then the narrative entered in the metadata element description is relative to the related media items that together constitute a collected works or standalone aggregation of materials

"Series"
If you are earmarking a description as a "Series," then the narrative entered in the metadata element description is relative to an overview of all the combined episodes found within that series.

"Episode"
If you are earmarking a description as an "Episode," then the narrative entered in the metadata element description is relative to a specific episode or program that is part of a larger series of related program or media items.

"Program"
If you are earmarking a description as a "Program," then the narrative entered in the metadata element description is relative to a specific, standalone media item that is not part of any series or collection of related items.

"Segment"
If you are earmarking a description as a "Segment," then the narrative entered in the metadata element description is relative to a specific, logical chapter or self-contained sequence with a discernable beginning, middle, and end for its intellectual content. In describing a sequence of stand-alone segments, use the descriptionType "Segment Sequence."

"Clip"
If you are earmarking a description as a "Clip," then the narrative entered in the metadata element description is relative to a portion of a larger media item. Clip is a term with specific meaning and semantic importance for video and audio materials, especially when used in editing.

"Selection or Excerpt"
If you are earmarking a description as a "Selection or Excerpt ," then the narrative entered in the metadata element description is relative to a small extraction of material from a larger media item. Selections and Excerpts are typically smaller in scope than Segments or Clips, and are intended to represent a snippet of content.

"Table of Contents"
If you are earmarking a description as a "Table of Contents," then the narrative entered in the metadata element description contains some sort of outline or sequential list of headings identifying a representative name for chunks of content found within a media item. If the scope of the Table of Contents is lengthy, consider generating a separate stand-alone media item (e.g., PDF or Text) and catalog it as another instantiation of the original asset.

"Segment Sequence "
If you are earmarking a description as a "Segment Sequence," then the narrative or index entered in the metadata element description displays each of the stand-alone segments or parts, possibly identifying them by order, name or title, time stamp, and an individual segment description. If the scope of the Segment Sequence is lengthy, consider generating a separate stand-alone media item (e.g., PDF or Text)and catalog it as another instantiation of the original asset. 

"Rundown"
If you are earmarking a description as a "Rundown," then the narrative entered in the metadata element description contains a time sequence of discernable and distinct portions of a total media item's content. If the scope of the Rundown is lengthy, consider generating a separate stand-alone media item (e.g., PDF or Text) and catalog it as another instantiation of the original asset.

"Playlist"
If you are earmarking a description as a "Playlist," then the narrative entered in the metadata element description contains an organized compilation of separate media items assembled into a coherent presentation with related intellectual content. If the scope of the Playlist is lengthy, consider generating a separate stand-alone media item (e.g., PDF or Text) and catalog it as another instantiation of the original asset.

"Script"
If you are earmarking a description as a "Script," then the narrative entered in the metadata element description contains the original script for a media item. The metadata field description is likely to contain script material for very short duration media items, since databases on which MAM, DAM or CMS systems are implemented often limit the total number of characters allowed within a metadata field (typically no more than 4000 characters). If the Script is lengthy, consider generating a separate stand-alone media item (e.g., PDF or Text) and catalog it as another instantiation of the original asset.

"Transcript"
If you are earmarking a description as a "Transcript," then the narrative entered in the metadata element description contains a verbatim transcript for a media item. The metadata field description is likely to contain transcript material for very short duration media items, since databases on which MAM, DAM or CMS systems are implemented often limit the total number of characters allowed within a metadata field (typically no more than 4000 characters). If the Transcript is lengthy, consider generating a separate stand-alone media item (e.g., PDF or Text) and catalog it as another instantiation of the original asset.

"Descriptive Audio"
If you are earmarking a description as a "Descriptive Audio," then the narrative entered in the metadata element description contains specialized audio descriptions of screen activity and locations for a visual media item. The metadata field description is likely to contain descriptive audio material for very short duration media items, since databases on which MAM, DAM or CMS systems are implemented often limit the total number of characters allowed within a metadata field (typically no more than 4000 characters). If the Transcript is lengthy, consider generating a separate stand-alone media item (e.g., PDF or Text) and catalog it as another instantiation of the original asset.

"PODS"
If you are earmarking a description as "PODS," then the narrative entered in the metadata element description is relative to program information provided by PBS (Public Broadcasting Service) to its constituents in its Program Offer Data Service.

"PSD"
If you are earmarking a description as "PSD," then the narrative entered in the metadata element description is relative to the information provided by NPR (National Public Radio) to its constituents in its Program Service Data. [Each audio stream in an HD Radio multicast has a companion data stream which contains Program Service Data (PSD), often referred to as Program Associated Data (PAD), intended to describe or complement the audio program being heard by the listener.]

"Anecdotal Comments & Reflections "
If you are earmarking a description as "Anecdotal Comments & Reflections," then the narrative entered in the metadata element description contains additional remarks and opinions about a media item that are less suited to a formal "individual program description" but appropriate for enhancing the understanding of the nature, focus, and intent behind the intellectual content for a media item.

"Listing Services"
A full, rich program description is often offered on websites, viewer guides, and other promotional materials. However, the Listing Services and online electronic viewer guides use very abbreviated program descriptions, in addition to Genre tags, Date Created, and hosts/actors. The picklist for descriptionType includes the option "Listing Services" in order to identify the special, highly edited, short descriptions that are expected in program guides and schedules.

"Content Flags "
If you are earmarking a description as "Content Flags," then the narrative entered in the metadata element description identifies (by description and/or timestamps) content of a questionable (or for some communities, offensive and objectionable) nature or language.

"Other"
An "Other" option is provided to accommodate other types of descriptions that PBCore cannot envision at this time or that is required by another organization or community.

PBCore supplies its own picklist of terms that are alligned with TiVo, the Tribune Media tags, and the PBS Program Offer Data Service (PODS).

If another picklist is employed, it is important that its authority be identified by using this metadata field.

Use a URL where possible or practical when identifying the genre authority used. If the authority is identified by a personal name or corporporate/organizational name, PBCore recommends the following rules to specify the authority:

FOR PERSONAL NAMES: Enter personal names in inverted form using commas as indicated here:

• LastName, FirstName MiddleName, Suffix.
• Substitute a MiddleInitial for a MiddleName as appropriate, or ignore if not available.
• The suffix is any type of academic credential (Ph.D., Ed.D.) or familial lineage (Smithee, Alan, III)

FOR CORPORATE OR ORGANIZATIONAL NAMES: Enter corporate names in full direct form.

• Use the most specific and commonly used official name for an organization if it is distinctive enough to identify the group.
• If a particular subdivision of an organization is intended, identify both the more encompassing group as well as the subdivisions.
  • The hierarchy (main group and subdivision) starts with the main group, followed by <period space>, then the subdivision.
  • For example:
    • State of Utah. Film Commission
    • Smithee Productions. Educational Division
    • Wisconsin Public Television. Extension Division

The descriptor relationType identifies 12 ways in which the media item you are cataloguing is related by intellectual content to some other media item. For most information and digital asset management systems, the related item is its own asset and retains its own separate metadata record.

The distinguishing question to ask yourself is...

"Does this related media item share exactly the same intellectual content descriptions and intellectual property terms as the original media item?"

If the answer is "yes," then create a single PBCore metadata record, but repeat the container pbcoreInstantiation to indicate the existence of a different rendition of the same asset (e.g., a QuickTime and a WindowsMedia digital movie file; or a Beta-SP tape and a PDF transcript of the same program).

If the answer is "no," and the two media items are linked to one another, but do not share the same intellectual content and intellectual property descriptions, generate two separate PBCore metadata records. Document that the two media items and their metadata records are related by using the PBCore elements relationType and relationIdentifier.  

Once the type of relationship is identified, then the companion descriptor relationIdentifier is used to provide a name, locator, accession, identification number or ID where a related item can be obtained or found.

The bond between the media item you are cataloging and its related media item is selected from this list of 12 types:

"Has Format"
Used to indicate if the media item you are cataloging exists in another format, elsewhere. For example, your media item may be an interview segment, but it exists in another format, such as a documentary. Format, in this context, refers to the intellectual content and not another tape format or different rendition of a digital file.
