PROBLEM TO BE SOLVED: To obtain a recording medium for a signed hypertext which makes it possible to define various authorities to change respective properties in a document by providing a property definition part with a restriction condition definition part which defines the values of properties, the identifier of a link-destination document, and restriction conditions for the like-destination document. SOLUTION: The attribute definition part is provided with the restriction condition definition part which defines the values of the properties, the identifier of the link- destination document, and the restriction conditions for the link-destination document. For example, a signed document 200 consists of a schemer ID 201, a document ID 202, an issuer ID 203, a body 204, and the sign 205 of the issuer for them. The body 204 consists of >=0 property definition parts 206 and 207. Further, those property definition parts 206 and 207 are defined by a group of an attribute name and a value or a group of the attribute name, the value, a link-destination document ID, and the restriction condition definition part. The restriction condition definition part defines the structure of the link-destination document and the restriction conditions for limiting the attribute values. |
