A dictionary object is an associative table containing pairs of objects, known as the dictionary’s entries. The first element of each entry is the key and the second element is the value. The key must be a name. The value can be any kind of object, including another dictionary. A dictionary entry whose value is null is equivalent to an absent entry. (This differs from PostScript, where null behaves like any other object as the value of a dictionary entry.) The number of entries in a dictionary is subject to an implementation limit; Dictionary objects are the main building blocks of a PDF document. They are commonly used to collect and tie together the attributes of a complex object, such as a font or a page of the document, with each entry in the dictionary specifying the name and value of an attribute. By convention, the Type entry of such a dictionary identifies the type of object the dictionary describes. In some cases, a Subtype entry (sometimes abbreviated S) is used to further identify a specialized subcategory of the general type. The value of the Type or Subtype entry is always a name. For example, in a font dictionary, the value of the Type entry is always Font, whereas that of the Subtype entry may be Type1, TrueType, or one of several other values.

The value of the Type entry can almost always be inferred from context. The operand of the Tf operator, for example, must be a font object; therefore, the Typeentry in a font dictionary serves primarily as documentation and as information for error checking. The Type entry is not required unless so stated in its description; however, if the entry is present, it must have the correct value. In addition, the value of the Type entry in any dictionary, even in private data, must be either a name defined in this book or a registered name.
