Methods

Create()

public static XMPMeta Create()

Returns

XMPMeta

Returns an empty XMPMeta-object.

GetSchemaRegistry()

public static XMPSchemaRegistry GetSchemaRegistry()

Returns

XMPSchemaRegistry

Returns the singleton instance of the XMPSchemaRegistry.

GetVersionInfo()

Obtain version information.

public static XMPVersionInfo GetVersionInfo()

Returns

XMPVersionInfo

Returns the version information.

Remarks

Obtain version information. The XMPVersionInfo singleton is created the first time its requested.

Parse(Stream)

Parsing with default options.

public static XMPMeta Parse(Stream @in)

Parameters

in Stream

an InputStream

Returns

XMPMeta

Returns the XMPMeta-object created from the input.

See Also

Parse(Stream, ParseOptions)

Parse(Stream, ParseOptions)

These functions support parsing serialized RDF into an XMP object, and serailizing an XMP object into RDF.

public static XMPMeta Parse(Stream @in, ParseOptions options)

Parameters

in Stream

an InputStream

options ParseOptions

Options controlling the parsing.
The available options are:

• XMP_REQUIRE_XMPMETA - The <x:xmpmeta> XML element is required around <rdf:RDF>.
• XMP_STRICT_ALIASING - Do not reconcile alias differences, throw an exception.

Note:The XMP_STRICT_ALIASING option is not yet implemented.

Returns

XMPMeta

Returns the XMPMeta-object created from the input.

Remarks

These functions support parsing serialized RDF into an XMP object, and serailizing an XMP object into RDF. The input for parsing may be any valid Unicode encoding. ISO Latin-1 is also recognized, but its use is strongly discouraged. Serialization is always as UTF-8.
parseFromBuffer() parses RDF from an InputStream. The encoding is recognized automatically.

ParseFromBuffer(byte[])

Parsing with default options.

public static XMPMeta ParseFromBuffer(byte[] buffer)

Parameters

buffer byte[]

a String contain an XMP-file.

Returns

XMPMeta

Returns the XMPMeta-object created from the input.

See Also

ParseFromBuffer(byte[], ParseOptions)

ParseFromBuffer(byte[], ParseOptions)

Creates an XMPMeta-object from a byte-buffer.

public static XMPMeta ParseFromBuffer(byte[] buffer, ParseOptions options)

Parameters

buffer byte[]

a String contain an XMP-file.

options ParseOptions

Options controlling the parsing.

Returns

XMPMeta

Returns the XMPMeta-object created from the input.

See Also

Parse(Stream, ParseOptions)

ParseFromString(string)

Parsing with default options.

public static XMPMeta ParseFromString(string packet)

Parameters

packet string

a String contain an XMP-file.

Returns

XMPMeta

Returns the XMPMeta-object created from the input.

See Also

Parse(Stream)

ParseFromString(string, ParseOptions)

Creates an XMPMeta-object from a string.

public static XMPMeta ParseFromString(string packet, ParseOptions options)

Parameters

packet string

a String contain an XMP-file.

options ParseOptions

Options controlling the parsing.

Returns

XMPMeta

Returns the XMPMeta-object created from the input.

See Also

ParseFromString(string, ParseOptions)

Reset()

Resets the schema registry to its original state (creates a new one).

public static void Reset()

Remarks

Resets the schema registry to its original state (creates a new one). Be careful this might break all existing XMPMeta-objects and should be used only for testing purpurses.

Serialize(XMPMeta, Stream)

Serializes an XMPMeta-object as RDF into an OutputStream with default options.

public static void Serialize(XMPMeta xmp, Stream @out)

Parameters

xmp XMPMeta

a metadata object

out Stream

an OutputStream to write the serialized RDF to.

Serialize(XMPMeta, Stream, SerializeOptions)

Serializes an XMPMeta-object as RDF into an OutputStream.

public static void Serialize(XMPMeta xmp, Stream @out, SerializeOptions options)

Parameters

xmp XMPMeta

a metadata object

out Stream

an OutputStream to write the serialized RDF to.

options SerializeOptions

Options to control the serialization (see SerializeOptions ).

SerializeToBuffer(XMPMeta, SerializeOptions)

Serializes an XMPMeta-object as RDF into a byte buffer.

public static byte[] SerializeToBuffer(XMPMeta xmp, SerializeOptions options)

Parameters

xmp XMPMeta

a metadata object

options SerializeOptions

Options to control the serialization (see SerializeOptions ).

Returns

byte[]

Returns a byte buffer containing the serialized RDF.

SerializeToString(XMPMeta, SerializeOptions)

Serializes an XMPMeta-object as RDF into a string.

public static string SerializeToString(XMPMeta xmp, SerializeOptions options)

Parameters

xmp XMPMeta

a metadata object

options SerializeOptions

Options to control the serialization (see SerializeOptions ).

Returns

string

Returns a string containing the serialized RDF.

Remarks

Serializes an XMPMeta-object as RDF into a string. Note: Encoding is ignored when serializing to a string.
