Module `Ldp.Ct`Source

Simple content-type parsing/printing. Tries to implement RFC 2045.

Base types

Sourcetype token = string

Non-empty string containing only ascii CHAR except SPACE, CTLs, or tspecials as defined here.

Sourcetype ty =

| Application
| Audio
| Ietf of token
| Image
| Message
| Multipart
| Text
| Video
| X of token

Sourcetype subty = token

Sourcetype value =

| T of token
| Quoted of string

Sourcetype parameter = token * value

Sourcetype error = string * Lexing.position

Sourceval string_of_error : error -> string

Content-types

Sourcetype t = {

ty : ty;
subty : subty;
parameters : parameter list;

}

Sourceval create : ?parameters:parameter list -> ty -> subty -> t

create ?paramers ty subty creates a new content-type.

Sourceval default : t

Default content-type is text/plain with charset parameter set to "us-ascii".

Sourceval of_string : string -> (t, error) result

Sourceval to_string : t -> string

Sourceval value : token -> t -> string option

value p t returns value associated to parameter p in t, if any.

Sourceval value_def : token -> string -> t -> string

value p def t returns value associated to p in t, or def if there is no parameter p in t.

Sourceval charset : t -> string option

Same as value but for parameter "charset".

Sourceval charset_def : string -> t -> string

Same as value_def but for paramter "charset".

Mime-types

Sourcetype mime = ty * subty

Sourceval to_mime : t -> mime

Sourceval of_mime : mime -> t

Sourceval mime_to_string : mime -> string

Sourceval mime_of_string : string -> (mime, error) result

Sourceval has_mime : t -> mime -> bool

has_mime ct mime returns true is type and subtype of mime are the same as in ct, else false.

Predefined content-types

Sourceval ct_turtle : t

text/turtle

Sourceval ct_xmlrdf : t

application/rdf+xml

Sourceval ct_sparql_update : t

application/sparql-update

Sourceval ct_text : t

text/plain

Sourceval ct_xhtml : t

application/xhtml+xml

Predefined mime-types

Sourceval mime_turtle : mime

text/turtle

Sourceval mime_xmlrdf : mime

application/rdf+xml

Sourceval mime_sparql_update : mime

application/sparql-update

Sourceval mime_text : mime
