Overview

Package licensing implements support for KBART and ISIL attachments. KBART might contains special fields, that are important in certain contexts. Example: "Aargauer Zeitung" could not be associated with a record, because there is no ISSN. However, there is a string "https://www.wiso-net.de/dosearch?&dbShortcut=AGZ" in the record, which could be parsed to yield "AGZ", which could be used to relate a record to this entry (e.g. if the record has "AGZ" in a certain field, like x.package).

type Embargo

type Embargo string

Embargo holds moving wall information.

http://www.uksg.org/kbart/s5/guidelines/data_fields

The embargo field reflects limitations on when resources become available online, generally as a result of contractual limitations established between the publisher and the content provider. Presenting this information to librarians (usually via link resolver owners) is vital to ensure that link resolvers do not generate links to content that is not yet available for users to access.

One of the biggest problems facing members of this supply chain is that multiple kinds of embargoes exist—in some cases, coverage "to one year ago" means that data from 365 days ago becomes available today, while in other cases it means that the item is not available until the end of the current calendar year.

Because of the complexities of embargoes, we recommend that the ISO 8601 date syntax should be used. This is flexible enough to allow multiple types of embargoes to be described.

The following method for specifying embargoes is derived from the ISO 8601 "duration syntax" standard, making a few additional distinctions not covered in the standard. The embargo statement has three parts: type, length, and units. These three parts are written in that order in a single string with no spaces.

* Type: All embargoes involve a "moving wall", a point in time expressed relative to
        the present (e.g., "12 months ago"). If access to the journal begins at the moving
        wall, the embargo type is "R". If access ends at the moving wall, then the
        embargo type is "P".
* Length: An integer expressing the length of the embargo
* Units: The units for the number in the "length" field: "D" for days, "M" for months,
         and "Y" for years. For simplicity, "365D" will always be equivalent to one year,
         and "30D" will always be equivalent to one month, even in leap years and months
         that do not have 30 days.

The "units" field also indicates the granularity of the embargo, that is, how frequently the moving wall "moves". For example, a newspaper database may have a subscription model that gives customers access to exactly one year of past content. Each day, a new issue is added, and the issue that was published exactly one year ago that day is removed from the customer’s access. In this case, the embargo statement would be "R365D", because the date of the earliest accessible issue changes each day.

Another journal may have a model that gives access to all issues in the current year, starting in January. The following January, the customer loses access to all of the previous year’s issues at once, and will only be able to access issues published in the current year. In this case, we would say that the customer has access to one "calendar year" of content. The embargo statement would be "R1Y", because the date of the earliest issue changes once a year.

Below are some common embargoes expressed according to this syntax:

* Access to all content, except the current calendar year: P1Y
* Access to all content in the previous and current calendar years: R2Y
* Access to all content from exactly 6 months ago to the present: R180D
* Access to all content, except the past 6 calendar months: P6M

In the case where there is an embargo at both the beginning and end of a coverage range, then two embargo statements should be concatenated, the starting embargo coming first. The two statements should be separated by a semicolon. For example, "R10Y;P30D" describes an archive in which the past 10 calendar years of content are available, except for the most current 30 days.

func (Embargo) AccessBeginsAtWall

func (embargo Embargo) AccessBeginsAtWall() bool

AccessBeginsAtWall returns true, if access begins at the moving wall.

func (Embargo) AccessEndsAtWall

func (embargo Embargo) AccessEndsAtWall() bool

AccessEndsAtWall returns true, if access end at the moving wall.

func (Embargo) Compatible

func (embargo Embargo) Compatible(t time.Time) error

Compatible returns true, if the given date is validated by the embargo relative to the current time.

func (Embargo) CompatibleTo

func (embargo Embargo) CompatibleTo(t time.Time, relative time.Time) error

CompatibleTo returns true, if the given date in validated by this embargo relative to another date.

func (Embargo) Duration

func (embargo Embargo) Duration() (dur time.Duration, err error)

Duration converts embargo like P12M, P1M, R10Y into a time.Duration. This duration will be positive. Time differences will have small shifts due to a month and a year being a fixed number of hours.

func (*Entry) Covers

func (entry *Entry) Covers(date, volume, issue string) error

Covers is a generic method to determine, whether a given date, volume or issue is covered by this entry. It takes into account moving walls. If values are not defined, we assume they are not constrained. It is an error, if the given date string cannot be parsed by one of the deposited layouts.

func (*Entry) ISSNList

func (entry *Entry) ISSNList() []string

ISSNList returns a list of unique, normalized ISSN (1234-567X) from various entry fields.
