]> Exif data description vocabulary An ontology to describe an Exif format picture data. All Exif 2.2 tags are defined as OWL properties (annotated by 'exif:exifNumber' in this vocabulary), as well as several terms to help this schema. Datatypes: - predefined interpretation of tag values are defined as domains of ObjectProperty. - other tags with a single numerical value are defined to have those datatypes as their domains: * Exif byte, short, long, signed long = xsd:integer. * Exif rational, signed rational = xsd:decimal. No datatype is defined for multiple numerical values such as three short of 'bitsPerSample' tag, becaus such values cannot be expressed with XMLSchema datatype. Also, no datatype is defined for Exif 'undefined' value type. Note that this vocabulary treats Exif ASCII type as plain literal, not xsd:string. Exifフォーマットの写真からデータを取りだしてRDFで表現するため、Exif 2.2の全てのタグをOWLプロパティとして定義し、それを記述するのに必要な語彙を追加したボキャブラリ。解釈が仕様で定義済みの整数値は統制語彙リソースとして、またそれ以外の数値をひとつだけ持つ場合はデータ型付きリテラルとして値域を定義している。文字列値を持つタグは基本的に値域を定義せず、プレーンリテラルとして扱う。 2003-07-18 2007-12-20 Version 2.13 - OWL DL version. 神崎正英 KANZAKI, Masahide IFD A specific data set of an image file, or 'Image File Data' (IFD). This corresponds to Exif-specific IFD (Image File Directory) defined in section 4.6.3 in the spec. While Image File 'Directory' is a data storage format, Image File 'Data' is a resource that represents a set of attributes of an image. Exif IFD An Exif data set of an image file, which corresponds to a set of tags for recording Exif-specific attribute information stored in Exif IFD (Image File Directory), as per section 4.6.3 A in the spec. GPS IFD A GPS data set of an image file, which corresponds to a set of tags for recording GPS information stored in GPS IFD (Image File Directory), as per section 4.6.3 B in the spec. Interoperability IFD An Interoperability data set of an image file, which corresponds to a set of tags to stores the information to ensure the Interoperability, and stored in Interoperability IFD (Image File Directory), as per section 4.6.3 C in the spec. PIM IFD A Print Image Matching data set of an image file, which corresponds to a set of tags to stores the information to print photos that more accurately reflect the original brightness and colors of the photographed image. In Exif file, it is stored in PrintImageMatching IFD (Image File Directory). Note that PrintImageMatching IFD is not a part of Exif 2.2 specification. Exif data A class of all Exif tag data. Exif support level A class of tag support level for each attribute, defined in section 4.6.8 in the spec. Unknown value A class of Exif tag values that are not defined in this vocabulary. It might be a reserved value in Exif 2.2 spec, or newly introduced Exif value, or some implementation specific value.

Recommended It is recommended to record the attribute in a given image. Optional It is optional whether to record the attribute in a given image. Not recorded The attribute is not recorded in a given image. JPEG marker The attribute is included in JPEG marker (and so not recorded in Exif IFDs). This vocabulary takes advantage of Exif's IFD (Image File Directory) to express structured data description. While TIFF 6.0 attribute tags can be regarded as properties of image itself, many of Exif-specific attributs such as flash or fNumber are propeties of picture taking condition, and GPS attributes are properties of a location. This vocabulary maps Exif directories to corresponding 'Image File Data' classes, and describes those class instances using properties in the IFD. Some tags have integer valuea whose interepretation are defined in the spec. In this vocabulary, those values are treated as controlled value resource, e.g. '#top-left' instead of integer value '1' for 'orientation' tag. この語彙は、ExifのIFDを利用して構造化したデータ記述を行います。Exifタグのうち、TIFF由来のものは画像自身のプロパティとみなすことができますが、Exif固有タグの多く、たとえばflashやfNumberなどは、撮影条件を表すプロパティであり、GPSタグは撮影場所のプロパティといえます。そこで、この語彙はExifのIFDに対応する'Image File Data'クラスを用い、IFD内のタグはそのクラスインスタンスのプロパティとして表現します。なお、整数値で記録されるExifタグの多くはその解釈が仕様で定められているので、この語彙では、'orientation'の値を'1'とするのではなく、'#top-left'と定義しています。 exif: Canon Canon IXY DIGITAL 30 0.0025 3.5 9.1875 ]]> A more complehensive example.
