GUIDELINES
FOR USAGE

Help

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 small 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 or index 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 Descriptive Audio 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.
