Transkribus specific metadata for this transcript Alternative document page images (e.g. black-and-white) Unassigned regions are considered to be in the (virtual) default layer which is to be treated as below any other layers. For generic use Page type Pure text is represented as a text region. This includes drop capitals, but practically ornate text may be considered as a graphic. The angle the rectangle encapsulating a region has to be rotated in clockwise direction in order to correct the present skew (negative values indicate anti-clockwise rotation). Range: -179.999,180 The nature of the text in the region The degree of space in points between the lines of text (line spacing) The direction in which text in a region should be read (within lines) The angle the baseline of text withing a region has to be rotated (relative to the rectangle encapsulating the region) in clockwise direction in order to correct the present skew (negative values indicate anti-clockwise rotation). Range: -179.999,180 Defines whether a region of text is indented or not Text align The primary language used in the region The secondary language used in the region The primary script used in the region The secondary script used in the region Point list with format "x1,y1 x2,y2 ..." Multiple connected points that mark the baseline of the glyphs from left to right Overrides primaryLanguage attribute of parent text region Overrides the production attribute of the parent text region For generic use Overrides primaryLanguage attribute of parent line and/or text region Overrides the production attribute of the parent text line and/or text region. For generic use Overrides the production attribute of the parent word / text line / text region. For generic use Text in a "simple" form (ASCII or extended ASCII as mostly used for typing). I.e. no use of special characters for ligatures (should be stored as two separate characters) etc. Correct encoding of the original, always using the corresponding Unicode code point. I.e. ligatures have to be represented as one character etc. OCR confidence value (between 0 and 1) An image is considered to be more intricate and complex than a graphic. These can be photos or drawings.

Range: -179.999,180 The type of chart in the region An approximation of the number of colours used in the region The background colour of the region Specifies whether the region also contains text Separators are lines that lie between columns and paragraphs and can be used to logically separate different articles from each other. The angle the rectangle encapsulating a region has to be rotated in clockwise direction in order to correct the present skew (negative values indicate anti-clockwise rotation). Range: -179.999,180 The colour of the separator Regions containing equations and mathematical symbols should be marked as maths regions. The angle the rectangle encapsulating a region has to be rotated in clockwise direction in order to correct the present skew (negative values indicate anti-clockwise rotation).

The angle the rectangle encapsulating a region has to be rotated in clockwise direction in order to correct the present skew (negative values indicate anti-clockwise rotation). Range: -179.999,180 The background colour of the region Regions containing advertisements. The angle the rectangle encapsulating a region has to be rotated in clockwise direction in order to correct the present skew (negative values indicate anti-clockwise rotation). Range: -179.999,180 The background colour of the region Noise regions are regions where no real data lies, only false data created by artifacts on the document or scanner noise. To be used if the region type cannot be ascertained. Determines the effective area on the paper of a printed page. Its size is equal for all pages of a book (exceptions: titlepage, multipage pictures). It contains all living elements (except marginals) like body type, footnotes, headings, running titles. It does not contain pagenumber (if not part of running title), marginals, signature mark, preview words. Definition of the reading order within the page. To express a reading order between elements they have to be included in an OrderedGroup. Groups may contain further groups. Numbered region Position (order number) of this item within the current hierarchy level. Indexed group containing ordered elements Position (order number) of this item within the current hierarchy level. Indexed group containing unordered elements Position (order number) of this item within the current hierarchy level. Numbered group (contains ordered elements) Numbered group (contains unordered elements) Border of the actual page (if the scanned image contains parts not belonging to the page). Can be used to express the z-index of overlapping regions. An element with a greater z-index is always in front of another element with lower z-index. Point list with format "x1,y1 x2,y2 ..." 4 indexes (i.e. positive integer values) separated by whitespaces A single point" Container for one-to-one relations between layout objects (for example: DropCap - paragraph, caption - image) One-to-one relation between to layout object. Use 'link' for loose relations and 'join' for strong relations (where something is fragmented for instance). Examples for 'link': caption - image floating - paragraph paragraph - paragraph (when a pragraph is split across columns and the last word of the first paragraph DOES NOT continue in the second paragraph) drop-cap - paragraph (when the drop-cap is a whole word) Examples for 'join': word - word (separated word at the end of a line) drop-cap - paragraph (when the drop-cap is not a whole word) paragraph - paragraph (when a pragraph is split across columns and the last word of the first paragraph DOES continue in the second paragraph) For generic use Text production type Monospace (fixed-pitch, non-proportional) or proportional font For instance: Arial, Times New Roman. Add more information if necessary (e.g. blackletter, antiqua). Serif or sans-serif typeface The size of the characters in points The degree of space (in points) between the characters in a string of text Background colour Specifies whether the colour of the text appears reversed against a background colour For generic use TEI like tags, i.e. metadata information available to their corresponding element (i.e. in a TextRegion, TextLine or Word) like abbreviations, person names, gaps etc. Most tags correspond to a certain text range in their element, which is specified using the index and offset attributes Sub properties of this tag. E.g. when specifying a tag "abbrev" for tagging an abbreviation in the text, a sub-property could be the property "expansion" for the expansion of the abbreviation. Sub property nesting should not exceed child level one to prevent unnecessary complexity of the datastructure. name of the tag - this could pre specified tags like "abbrev", "gap" etc. or custom defined names a custom value element for the tag If this tag refers to some text in the corresponding element (i.e. in a TextRegion, TextLine or Word), this attribute specifies the 0 based starting index of the referenced text If this tag refers to some text in the corresponding element (i.e. in a TextRegion, TextLine or Word), this attribute specifies the length of the referenced text If this tag refers to some text in the corresponding element (i.e. in a TextRegion, TextLine or Word), this attribute specifies if it is a continuation from the previous element A property is a key/value pair storing information about the element it is in. Attributes are inherited to their child element and can be ovveridden there. The inheritance hierarchy is: Page -> Region -> TextLine -> Word -> Glyph key of the property - this could pre specified keys like "lang", "layout", "year_from", "year_to", "style", "weight" or meta data from the automatic process "editor", "editordate" or user defined properties "numbering" value to the corresponding key: for lang: "de", "us", according ISO 639.2 for year_(from|to): number for style: italic, normal for weight: bold, normal for layout: float, table, ... for numbering: 1,2,... for editor: "user name", "htr_process" ... Property names should be restricted to alphanumeric characters, underscores, dashes and dots. the link reference the link type the link description
