BIBFRAME concepts	MARC	Notes
type	Populated by the LDR(06) value, but possible to override based on one of the following 007 values: Globe: 007(00) Maps: 007(00) Motion Picture: 007(00) Nonprojected Graphic: 007(00) Projected Graphic: 007(00) Sound Recording: 007(00) For example, a LDR(06) = a creates a work.type = text. If the same record contains an 007(00) = a (Map), that will change the work.type = Cartography. See BF conversion specs for full details.	Distinguishes between a defined list of work types (text, audio, moving image, etc.).
aspectRatio	Populated from the following MARC tags: Motion Picture: 007(04)
classification	Populated from the following MARC tags: 050 055 060 070 082	Classifications are assigned a type value (e.g. classificationLcc), to distinguish between the different classification schemas. See conversion specs for more details.
colorContent	Populated from the following MARC tags: Electronic Resource: 007(03) Globe: 007(03) Maps: 007(03) Microform: 007(09) Motion Picture: 007(03) Nonprojected Graphic: 007(03) Projected Graphic: 007(03) Videorecording: 007(03)

legalDate	Populated by uniform titles (130, 240)

BIBFRAME concepts	MARC	Notes
type	The instance type can be populated by the following MARC tags: LDR (06-08) Electronic Resource: 007(00) BOOKS 008(23) = s or q There can only be one instance type, so in the event of multiple there is business logic to determine which is the "winner." See the BF conversion specifications for the tags above for more information.	Distinguishes between a defined list of instance types (print, electronic, manuscript, etc.). ONE Example - An instance would be classified as type = electronic if one of the following conditions is true: LDR (06) = m, indicating a computer file 007 (00) = c, indicating a computer file or electronic resource Other conditions can also impact type.

hasSeries	Populated by the 490 $avx and 830 $anpvx	A series statement is created from the 490 $av. The series enumeration, identifier, uniform title and other values are populated according to the BF conversion specification. Series information from the 490 and 830 MARC tags is stored in a `hasSeries` object on the Instance. The hasSeries object is only created if there is a 490$a in the record (no series info is stored if there is only an 830). If there is only a 490 tag (no 830 tag) in the ingested MARC record, the hasSeries object contains: label (490$a) seriesEnumeration (490$v) seriesStatement (490$a+$v) identifiedBy.value (490$x) (type=issn) If a corresponding 830 is present (paired to the 490 by order in file), the hasSeries object contains: label (490$a) seriesEnumeration (830$v, if present, else 490$v) seriesStatement (490$a+$v) identifiedBy.value (830$x, if present, else 490$x) (type=issn) instanceOf.title type = title mainTitle (830$a) partName (830$p) partNumber (830$n) label (830$adfgklmnoprs, concatenated with spaces) marcKey (entire 830 tag contents)

See conversion specs for more details.
illustrativeContent	Populated from the following MARC tags: Books: 008(18-21)
intendedAudience	Populated by the 521 tag. The intendedAudience.label is populated by the $a. The intendedAudience.source is populated by the $b. And the intendedAudience.note is populated based on the first indicator value, which indicates reading grade level, interest age level or interest grade level.

provisionActivity	Populated by both the 008 publication date, as well as the 257, 260, 261, 262, 264 tags. The 008(06) indicates the type of date provided and dicates the provisionActivity.type value. For example, an 008(06) = s creates a type = publication. An 008(06) = p creates a type = distribution. The 008(07-10) and 008(11-14) are used to populate the provisionActivity.date value. And the 008 (15-17) is used to populate the provisionActivity.place. See the BF conversion specs for the full details. The 257 $a populates a provisionActivity.place value. The 260 $abc will populate a type = publication, with a provisionActivity.place, provisionActivity.agent and provisionActivity.date respectively. The 260 $efg will populate a type = manufacture with a provisionActivity.place, provisionActivity.agent and provisionActivity.date respectively. The 261 $abdf will populate a type = publication, with a provisionActivity.agent (ab), provisionActivity.date (d) and provisionActivity.place (f). The 261 $e will populate a type = manufacture with a provisionActivity.agent. The 262 $abc will populate a type = publication, with a provisionActivity.agent (b), provisionActivity.date (c) and provisionActivity.place (a). The 264 $abc will populate a provisionActivity.place (a), provisionActivity.agent (b) and provisionActivity.date (c). The type of provisionActivity is dictated by the second indicator in the MARC tag (see BF specs).	Provides publication, manufacture and distribution details. The system supports storage of all provision activity data included in the record. When it comes to publication date information displayed in Vega Discovery, priority is given to dates populated by the 008 fixed fields.
