Value

Definition

First in field

1

Search term must be the first data in the field

First in subfield

Search term may appear in any subfield but must be the first data in the subfield in which it appears

Any position in field

3

Search term may appear any place in the field


A.4. Structure attributes


Structure

Value

Definition

Phrase

1

A phrase consists of one or more groups of characters separated by blanks (for example, ASCII hex "20"). The value to be searched is exactly as it appears in the search term with respect to order and adjacency. Word(s) in the phrase may be explicitly truncated. (See "Truncation" -- section 2.5 below.) To indicate that additional words may appear in the access point, use the completeness attribute.

Word

2

A word consists of a group of non-blank characters. It specifies the exact text of the value to be searched, unless the word is explicitly truncated. (See "Truncation" -- section 2.5 below.) A word search term contains no blanks.

Key

3

A key specifies a sequence of characters extracted from those characters contained in an indexed word but not necessarily representing complete words. In the term, key segments should be separated by a blank (ASCII hex "20"). Each key segment should be the length of the local key or the length of the word, to a maximum of 6 characters. (For example, an name/title derived key search term for "Copland, Aaron, 1900-Rodeo" could be "coplan rodeo".) A segment may be adjusted by the receiving agency to the length required for the receiver's indexes. For example, the following derived key searches are in use at LC and at OCLC (in Online System)

Year

4

A year search term is numeric and contains four digits.

Date
(normalized)

5

The day, month, year and time when a transaction or event takes place. The date search term structure is YYYYMMDDHHMMSSZ (YYYY = year; MM =month; DD = day; HH = hour; MM =minute; SS = second; Z = the time represented is Universal Time). The first four characters (YYYY) are mandatory.

Word list

6

A word list consists of one or more words separated by blanks (for example, ASCII hex "20"). No order of the words is implied. The attributes (other than structure) that are associated with the search term apply to each word in the word list. Any words in a word list may be explicitly truncated. (See "Truncation" -- section 2.5 below.)

Date
(un-normalized)

100

The day, month, and year when a transaction or event takes place. The un-normalized search term is unstructured.

Name
(normalized)

101

A name search term that is structured in a particular order (e.g., last_name, first_name). The resulting term is subject to special matching rules on the target system that differ from those applied to names structured as phrases or unstructured names.

Name
(un-normalized)

102

A name search term that is unstructured (e.g., first_name last_name), however, the resulting term is subject to matching rules on the target system that differ from those applied to phrases or structured names (e.g., the term "john smith" might be searched by the target as "smith, j#").

Structure

103

The term has a structure that is either implied by the Use attribute or defined by the target.

Urx

104

The term is a document identifier, for example, an identifier extracted from a Z39.50 URL.

Free-form-text

105

The term is text, input by the end user. May be used, for example, for relevance feedback.

Document-text

106

The term is text, extracted from a document. May be used, for example, for relevancefeedback.

Local-number

107

A number significant to the target.

String

108

The entire term is to be treated as a string, rather than a sequence or set of individual words

Numeric string

109

The term is a character string that represents a number


A.5. Truncation attributes


Truncation

Value

Structure

Definition

Right truncation

1

Word or Phrase

Last word of term is right truncated

String

Entire term is right truncated.

Word list

Each word is right truncated.

Left truncation

2

Word or Phrase

First word of term is left truncated.

String

Entire term is left truncated.

Word list

Each word is left truncated.

Left and right truncation

3

Word or Phrase

First word of term is left truncated and last word of term is right truncated.

String

Entire term is left and right truncated.

Word list

Each word is left and right truncated.

Do not truncate

100




No truncation is to be applied.

Process # in search term

101




The search term contains the symbol "#" (ASCII hex "23") to show where truncation will take place (e.g., "National H# Institute", or "d#on").

RegExpr-1

102




The term is in the form of a regular expression as prescribed by IEEE 1003.2 Volume 1, Section 2.8 "Regular Expression Notation".

RegExpr-2

103




The term is in the form of a regular expression whose format is target-defined.

A.6. Completeness attributes


Completeness

Value

Definition

Incomplete subfield

1

Words other than those in the search term may appear in the subfield or field in which the term appears.

Complete subfield

2

No words other than those in the search term should appear in the entire subfield in which the term appears, but additional words may appear in other subfields in the field.

Complete field

3

No words other than those in the search term should appear in the entire field in which the term appears.
