NLMCatalogRecordSet XML Element Descriptions Used in CatfilePlus and Serfile

The elements presented in this document are defined in the NLMCatalogRecordSet.dtd and are used in the CatfilePlus and Serfile XML output files. The NLMCatalogRecordSet.dtd is available at http://www.nlm.nih.gov/databases/dtd/. An alphabetical list of all element names in the NLMCatalogRecordSet.dtd is available at http://www.nlm.nih.gov/bsd/licensee/catrecordxml_elementlist_alpha2.html. An alphabetical list and description of all element attribute vales is available at http://www.nlm.nih.gov/bsd/licensee/catrecordxml_attributevalues_alpha2.html.

Structure of the NLMCatalogRecordSet.dtd:
The NLMCatalogRecordSet.dtd defines a XML structure for bibliographic records in LocatorPlus. At the highest level, the DTD requires a root element named “NLMCatalogRecordSet.” The <NLMCatalogRecordSet> root element is comprised of one or more instances of the top-level <NLMCatalogRecord> element, and may optionally contain one instance of the top-level <DeleteCatalogRecord> element.

Each <NLMCatalogRecord> element describes a single bibliographic item and is the equivalent of a single LocatorPlus bibliographic record. The <NLMCatalogRecord> element is comprised of a combination of child elements that describe specific aspects of the bibliographic item, such as title, author, and subject. <NLMCatalogRecord> and its child elements are defined and described in this document.

The <DeleteCatalogRecord> element is present in the <NLMCatalogRecordSet> when bibliographic records have been deleted from LocatorPlus. The <DeleteCatalogRecord> element contains only the unique identifier of each deleted record and is defined more fully at the end of this document.

Structure of the element descriptions in this document:
Following a description of the <NLMCatalogRecord> parent element, this document continues with descriptions of its 48 child elements based on their order in CatfilePlus and Serfile XML files. The <NLMCatalogRecord> child elements are numbered for convenience and readability.

Some of the <NLMCatalogRecord> child elements contain child elements of their own. These “sub-elements” are defined and described within the description of their parent elements.

Each of the 48 numbered sections includes the following information, if applicable:

  • Required indicates Yes/No whether or not the element is required to appear within its parent envelope
  • Repeatable indicates Yes/No whether or not the element can be repeated within its parent envelope
  • Child elements are elements contained within a parent element envelope
  • Attributes are applied to an element to provide additional information about that element; each attribute links to a detailed description in the Alphabetical List of Attributes Used in the NLMCatalogRecord
  • A brief description of the element and its content
  • MARC 21 source provides a description or link to a description of the MARC 21 source of the data (for additional information on MARC 21, see http://www.loc.gov/marc/marcdocz.html)
  • Additional information/background provides contextual information that may be useful toward understanding the intent or purpose of the element

About Examples:
In most cases, multiple examples are given within the Examples section. When an example shows multiple occurrences of the same element without intervening blank lines, the intent is to demonstrate that the element repeats within a single parent envelope. Examples with blank lines between multiple occurrences of the same element indicate distinct instances of that element from different parent envelopes.

About the character set:
Information about the character set used in NLMCatalogRecordSet.dtd is at http://www.nlm.nih.gov/bsd/licensee/catrecordxml_characterset2.html

Element Descriptions


I. <NLMCatalogRecord>

Required: Yes
Repeatable: Yes
Attributes: Owner, Status
Child Elements: See numbered elements 1-48 below

<NLMCatalogRecord>, a top-level or parent element within <NLMCatalogRecordSet>, encloses or envelopes a single bibliographic record.

Each <NLMCatalogRecord> is derived from one new or updated LocatorPlus record.

Required: Yes
Repeatable: No
Attributes: (none)
Child Elements: (none)

The <NLMUniqueID> is the 7-9 digit alpha-numeric identifier used to uniquely identify every record in LocatorPlus; therefore, it also is used to uniquely identify each <NLMCatalogRecord>.

Example(s):

MARC 21 source: Field 035 subfield 9 (local field in LocatorPlus).

Additional information/background:
For catalog records initiated in NLM's cataloging, acquisitions or serial record systems prior to Fall 1998, the <NLMUniqueID> may be 7 to 9 digits in length; the terminal digit may be numeric or the alphabetic characters "A" or "R".

Beginning with NLM's implementation of the LocatorPlus integrated library system in Fall 1998, each record initiated in or loaded from NLM or collaborative partner databases has an <NLMUniqueID> consisting of 9 numerics.

<NLMUniqueID> may be used to locate the bibliographic record in LocatorPlus at http://locatorplus.gov/ where the user can have access to NLM holdings and item information.

<NameQualifier> contains the fuller form of the <Forename> value if available.
<TitleAssociatedWithName> contains a uniform title, title part of a work, or series title associated with this author (used to co-locate by name/title combinations).
<OtherInformation> contains any remaining author data of importance from the LocatorPlus record, including any suffix-like data not included in <Suffix>.
<Affiliation> the name of or abbreviation for the organization that the researcher was affiliated with at the time the work was written.
<Role> indicates the contribution made to the resource by the author, e.g., author, illustrator, editor, etc.

B. Each collective or corporate name may be comprised of the following group of <Author> child elements:
<CollectiveName> contains the corporate, jurisdiction, or meeting name followed by the name(s) of subordinate unit(s), as appropriate.
<OtherInformation> contains related information dependent on the type of collective or corporate name, such as, the location and/or date of a meeting or the number of a part/section/meeting.
<TitleAssociatedWithName> contains a uniform title, title part of a work, or series title associated with this author (used to co-locate by name/title combinations).

Additional information/background:
The contents of the <Initials> element is constructed from the data going to the <Forename> element. An individual initial is found at the beginning of the <Forename> string or following a break. A break is a space or hyphen. Only capital letters in <Forename> are candidates for initials except for the letter following a hyphen. The letter following a hyphen is a candidate for an initial unless the string following the hyphen is 'ichi'. If <Forename> is only initials, there will be spaces between initials. Initials include the following particles: de, do, da, du, del, dos, el-, le and el. All except 'el-' are followed by a space and are preceded by a space or are at the beginning of the name string. All particles are converted to lower case in the <Initials> element. If language is Bulgarian, Russian, Serbo-Croatian (Roman), or Ukrainian, then the <Initials> element content may be a 2-4 character transliterated mixed-case initial.

<PublicationInfo> is an envelope for a number of child elements containing information regarding the publication of the resource.

The values in <Country> are found in the MARC Country Code list, Part 1: Name List at http://www.loc.gov/marc/countries/cou_pt1names.html. The two or three-digit <PlaceCode> reflects the MARC Country code list, Part II: Code Sequence at http://www.loc.gov/marc/countries/cou_pt2codes.html.

If the place of publication is unknown, the <PlaceCode> will contain "xx" (the code for unknown) and there will be no value in the <Country> element.

If the place of publication is within the United States, the <PlaceCode> may contain a specific three-digit state code (such as "mdu" for Maryland) or the more generic "xxu" (meaning "United States, location not further specified"). In each case, however, <Country> will be United States. Provinces in Canada and the parts of the United Kingdom and Australia are handled similarly.

The data from the Imprint Statement in LocatorPlus is parsed into three separate elements: <Place>, <Publisher>, and <DateIssued>. Those same values also are grouped collectively in <Imprint>.

There may be multiple occurrences of <Imprint>, <Place>, <Publisher>, and <DateIssued> for both the original and current data.

<ProjectedPublicationDate> gives the anticipated 2-digit year and 2-digit month of publication, as announced by the publisher. It exists only on records created by NLM at the pre-publication stage and is removed if/when NLM subsequently acquires and catalogs the material.

<PublicationFirstYear> and <PublicationEndYear> each contains 4 characters; unknown digits are indicated with the letter 'u'.

<PublicationFirstYear> occurs once in every record, unless the data source in the LocatorPlus record is totally blank (allowed only for B.C. publication dates). In that case, there is no <PublicationFirstYear> element in the record.

The <PublicationEndYear> element occurs in a record when one of the following conditions exists:

  • <Issuance> is continuing. If the work is still published ("open"), the <PublicationEndYear> value will be 9999.
  • <Issuance> is monographic but publication occurred over a period of years. In this case, the <PublicationFirstYear> and <PublicationEndYear> will give the range of publication dates.
  • <Issuance> is monographic but the single publication date is questionable. In this case, the <PublicationFirstYear> and <PublicationEndYear> will give the range of possible publication dates.
  • <Issuance> is monographic and the LocatorPlus record contains a reprint/reissue date in addition to the original publication date. This situation is identifiable when the value in <PublicationFirstYear> is greater than the value in <PublicationEndYear>.

<Edition> contains information relating to the edition of the work.

<DatesOfSerialPublication> contains information about the beginning and/or ending dates (which may include textual information, such as “began with” or “ceased with”) or sequential designations (such as volume/issue) of the resource being described.

<Frequency> contains information about the frequency of publication of a serial. While only one current frequency is allowed, the element is repeated for each former frequency.

<IndexingSourceList> is an envelope containing elements used to specify the publications or databases in which a title has been indexed and/or abstracted, if known.

Within the <IndexingSourceList> envelope, separate occurrences of <IndexingSource>, with its child elements <IndexingSourceName> and <Coverage>, are used to identify multiple indexing sources and, optionally, the extent of the resource covered by the indexing source.

For non-serial material held by NLM's History of Medicine Division (HMD), the <IndexingSourceList> contains a reference to a published description of that item in a standard source. All data is concatenated in <IndexingSourceName>; <Coverage> is not used for HMD materials.

NLM's controlled topical subject vocabulary, Medical Subject Headings (MeSH®), is used to characterize the subject content of works in LocatorPlus. See http://www.nlm.nih.gov/mesh/meshhome.html for information about MeSH.

When MeSH headings have been assigned to a LocatorPlus record, <MeshHeadingList> provides an envelope for each heading within its <MeshHeading> child element.

The <MeshHeading> element itself is a parent element for the following child elements:
<DescriptorName> contains MeSH “Descriptors” or main subjects.
<QualifierName> contains “Qualifiers” to the MeSH Descriptors. A qualifier indicates that the subject in <DescriptorName> is limited or specific to a particular aspect.
Example(s):

<OtherSubjectList> is an envelope for subject information which does not qualify for inclusion in the elements <MeshHeadingList>, <PersonalNameSubjectList>, <SpaceFlightMission>, <KeywordList> or <ChemicalList>. <OtherSubjectList> is repeated for each different subject owner or source.

On records cataloged by NLM, the large majority of LocatorPlus data contained in <OtherSubjectList> are Corporate or Meeting names and Uniform titles used as subjects. On records owned by or shared with collaborative partners or the NLM Staff Library, the terms in <OtherSubjectList> may also be Library of Congress subject headings (LCSH), geographic terms not included in MeSH, or other special vocabulary.

<OtherSubjectList> contains the <OtherSubject> element, which is in turn an envelope for the following child elements:
<OtherSubjectName> contains the main subject term.
<OtherInformation> may contain a subject qualifier, subordinate term, or any other information associated with the subject.
<TitleAssociatedWithName> contains a title associated with the subject.

28. <SpaceFlightMission>

Required: No
Repeatable: Yes
Attributes: (none)
Child Elements: (none)

<SpaceFlightMission> is used exclusively by the NLM collaborative partner NASA. This element contains the space flight mission name and/or number when results of research conducted in space are covered in a publication.

Following the pattern established in the MEDLINE XML records, in cases where there are multiple space flight missions, a specific mission name is not directly linked to the descriptive values manned/unmanned or long/short duration, as they are in LocatorPlus. For records containing more than one Space Flight Mission name, see the Space Flight Mission Summary Table at http://www.nlm.nih.gov/bsd/space_flight.html that provides the manned/unmanned status and duration of each mission.

Example(s):
<SpaceFlightMission>Apollo Project</SpaceFlightMission>
<SpaceFlightMission>Biosatellite Project</SpaceFlightMission>
<SpaceFlightMission>Discoverer Project</SpaceFlightMission>
<SpaceFlightMission>Long duration</SpaceFlightMission>
<SpaceFlightMission>Manned</SpaceFlightMission>
