Types

type Data

type Data struct {
	RelatedItems []RelItem    `xml:"relatedItem"`
	OriginInfos  []OriginInfo `xml:"originInfo"`
	Parts        []Part       `xml:"part"`
	Rights       string       `xml:"accessCondition"`
}

Data holds the meat of the issue XML

type DateIssued

type DateIssued struct {
	Date      string `xml:",chardata"`
	Qualifier string `xml:"qualifier,attr"`
}

DateIssued holds dates and qualifiers like "questionable"

type Detail

type Detail struct {
	Type    string `xml:"type,attr"`
	Number  string `xml:"number"`
	Caption string `xml:"caption"`
}

Detail holds numbers (which aren't really numbers) and captions. The type attribute tells us what the number and/or caption mean.

type Extent

type Extent struct {
	Unit  string `xml:"unit,attr"`
	Start string `xml:"start"`
}

Extent holds... a range maybe? I'm too lazy to look up the mods spec.

type ID

type ID struct {
	Label string `xml:",chardata"`
	Type  string `xml:"type,attr"`
}

ID represents an id label and an id type; for our uses this is primarily just the issue's LCCN

type OriginInfo

type OriginInfo struct {
	Dates []DateIssued `xml:"dateIssued"`
}

OriginInfo holds issue date and date-as-labeled

type Part

type Part struct {
	Details []Detail `xml:"detail"`
	Extents []Extent `xml:"extent"`
}

Part seems to hold a lot of very generic information that can only be made sense of in context

type RelItem

type RelItem struct {
	Type  string `xml:"type,attr"`
	IDs   []ID   `xml:"identifier"`
	Parts []Part `xml:"part"`
}

RelItem holds high-level issue metadata when in the issue metadata section; it's ignored for the page metadata
