The <feed> root #

Attribute	Use	Type	Meaning
`businessDate`	required	`xs:date`	The business date the data is for (YYYY-MM-DD).
`firm`	required	`xs:string`	Your firm code, shown on Data › Feeds (e.g. F00012).
`source`	optional	`xs:string`	Who produced the file (vendor or system name).
`generated`	required	`xs:dateTime`	When the file was produced (UTC).
`recordCount`	required	`xs:nonNegativeInteger`	The number of record elements. A file whose count does not match is refused (F004): it was probably cut short.
`mode`	optional (default delta)	`xs:string`	delta: only the records in the file change. full: the file is complete; records it does not list are inactivated, up to the feed's safety threshold.

The <record> elements #

upsert (insert or update by key). Elements may appear in any order; an element that is left out keeps its current value.

Element	Required	Type	Meaning	Codes
`code` key #	yes	`xs:string` pattern [A-Z0-9][A-Z0-9_.\-]{0,19}	Your code for the issuer. The key. A code: letters, digits, "_", "." or "-", up to 20. Part of the key. Example: `AAPL-INC`	`R101` `R111`
`name` #	yes	`xs:string` ≤ 120 chars	The issuer's legal name. Text, up to 120 characters. Example: `Apple Inc.`	`R101` `R114`
`country` #	no	`xs:string` pattern [A-Z]{2}	Country of incorporation (ISO 3166-1 alpha-2). An ISO 3166-1 alpha-2 country code, e.g. US. Example: `US`	`R108`
`lei` #	no	`xs:string` pattern [A-Z0-9][A-Z0-9_.\-]{0,19}	Legal Entity Identifier (20 characters). A code: letters, digits, "_", "." or "-", up to 20. Example: `HWUPKR0MPOU8FGXBT394`	`R111`
`parentCode` #	no	`xs:string` pattern [A-Z0-9][A-Z0-9_.\-]{0,19}	The parent issuer's code, if any. A code: letters, digits, "_", "." or "-", up to 20.	`R111`
`active` #	no	`xs:boolean`	false marks the issuer inactive. true or false. Example: `true`	`R112`
`udfs` #	no	`Udfs` up to 10 <udf slot="1..10" name="...">, ≤ 255 chars each	User-defined fields (format 1.1). Each <udf> names its slot (1 to 10) and optionally the field's name; the value is checked against the type your Admin gave the field. A slot that is not active for your firm is refused (U101), a value of the wrong type too (U102), and a name that differs from the slot's name (U103). Example: `<udf slot="1" name="Internal rating">BBB</udf>`	`U101` `U102` `U103` `U104`

Validation #

No DOCTYPE or entity declaration (F002); well-formed UTF-8 (F001).
The namespace and version are published (F007), and the file matches the XSD (F003).
Header: firm is your firm code (F006), businessDate a business day (F005), recordCount the number of records (F004).
Each record: the field checks in the table above, references to records that exist (R109), no key twice in a file (R110). A rejected record does not stop the rest of the file.

Codes this format can return: F001 F002 F003 F004 F005 F006 F007 F008 H201 R101 R108 R109 R110 R111 R112 R114 U101 U102 U103 U104
