A fuel rail formed by hydroforming. The hydroforming process includes applying a seal onto a fuel tube, and installing fuel injector blocks, including fuel injector ports, onto the tube in desired positions. The fuel tube assembly is placed in a die assembly, and pressurized fluid is supplied to the interior of the tube. The pressurized fluid causes the tube to expand outwardly into engagement with the blocks, and to pierce holes through the tube within each of the blocks to provide fluid communication with the associated fuel injector and other ports.

The method claimed in claim 1, wherein the preliminary metadata further comprises at least one of keywords, numerical goodness of fit scores associated with categories of the hierarchy for said keywords, and a title. 3. The method claimed in claim 1, wherein receiving data comprises receiving production data corresponding to a video program from a production system used to produce the video program, wherein generating preliminary metadata comprises generating preliminary metadata for a video programming event corresponding to a segment of the video program, wherein receiving user input comprises receiving user input specifying final metadata for the segment of the video program, and wherein storing the final metadata comprises storing the final metadata for transmission to receivers of the video programming event as metadata describing the subject matter of the segment of the video program. 4. The method claimed in claim 1, wherein the user input specifies at least one of a category that is not included in the preliminary metadata and is to be included in the final metadata, a category that is included in the preliminary metadata and is not to be included in final metadata, and a goodness of fit score to be associated with a category in the final metadata. 5. The method claimed in claim 1, wherein providing preliminary metadata comprises providing preliminary keywords, and wherein receiving user input specifying final metadata comprises receiving input selecting keywords. 6. The method claimed in claim 1, wherein providing preliminary metadata comprises providing a preliminary title, and wherein receiving user input specifying final metadata comprises receiving input specifying a title. 7. A programmable device for generating metadata that describes the subject matter of a video programming event, the device comprising a computer readable medium having stored therein programming instructions to perform data processing, the processing comprising: receiving data corresponding to the video programming event, the data including descriptive information and timing information; processing the received data to generate preliminary metadata describing the subject matter of the video programming event, the preliminary metadata comprising numerical goodness of fit scores associated with respective categories, wherein the numerical goodness of fit score associated with a category represents a degree to which the category is descriptive of the subject matter of the video programming event, and wherein the categories are arranged in a hierarchy comprising at least a set of top-level categories, respective sets of first level sub-categories each corresponding to and encompassed by a top level category, and respective sets of second level sub-categories each corresponding to and encompassed by a first level sub-category;
