56 Document format declaration inside Document and conformance checks change
57 during time. XML Schemas provide attribute for Document MIME type and Document
60 Attribute dmMimeType must present, but may be empty, may contain file name
61 extension, or may contain official MIME type. If MIME type is declared, ISDS
62 checks Document content for conformance to the MIME type.
64 There is MIME type blacklist: application/x-zip-compressed,
65 application/x-msdownload.
67 Attribute dmFileDescr (so called annotation) must present and must contain
68 file name of the Document. Even if dmMimeType exists, ISDS uses THIS attribute
69 to detect Document format (according file name extension) and checks content
70 for format conformance.
72 List of allowed MIME types is copied (and sometimes agumented) in appendix
73 of Webové služby rozhranní ISDS pro manipulaci s datovými zprávami.
75 There is list of allowed file name extensions and MIME type mapping

163 Document ::= Binary_Document | XML_Document
165 Document is Base64 encoded binary format or XML.
167 There exist special Document type, ESS format, that can exist in Content only
170 Note: ESS format is special XML language designed as interface between
171 Electronic Document Systems (ESS). It's defined in Appendix 4 of Provozní řád
174 Message with `malicious code' will be refused by ISDS.
176 Maximal total size of Documents in a Message is 10 MB. Binary document size is
177 size before encoding into Base64, XML document size is size in bytes as is
178 serialized inside SOAP request.
180 A Message can be addressed to 50 recipients at maximum.
182 Life time of Message:
184 – 90 days for delivered message, 100 days for system message
185 – unlimited for delivered through fiction messages, however they can be
186 moved to off-line storage after 90 days. User can request to move the
187 Message back into his box (off-line only currently).
189 Deleted messages are stored off-line as Envelope only without Content. Since
190 2010-06-01, some services has access to off-line stored envelopes
191 (Get(Signed)DeliveryInfo, MessageEnvelopeDownload, VerifyMessage,
192 AuthenticateMessage).
194 Note: Delivery through fiction is currently defined as new unread for more
195 than 10 days after delivery.
201 Some SOAP services (GetSignedDeliveryInfo etc.) returns response that embeds
202 digitally signed ISDS message or delivery info. The digital signature is
203 Base64-encoded BER CMS. (xmldsig is not used to avoid expensive XML
206 The CMS should carry one certificate and one signed body.
208 Since 2011-04, a time stamp is embedded into the CMS (get-message responses
209 currently only). The data structure is compliant with RFC 5126 (CMS Advanced
210 Electronic Signatures (CAdES)) and RFC 3161 (Internet X.509 Public Key
211 Infrastructure Time-Stamp Protocol (TSP)).
213 Stamp is stored in id-aa-signatureTimeStampToken object (iso(1).
214 member-body(2).us(840).rsadsi(113549).pkcs(1).pkcs-9(9).smime(16).
215 id-aa(2).14). Input for stamp is CMS SignerInfo.SignatureValue object.
217 Since 2014-09, the time stamp conforms to ATSv3 format defined by CAdES
218 Signatures Baseline Profile, ETSI TS 103 173, version 2.2.1. See
219 <http://webapp.etsi.org/workprogram/Report_WorkItem.asp?WKI_ID=41927>.
221 The signature and time stamp is computed on-the-fly, for each reponse again.
223 If time stamp authority is irresponsive, CMS without time stamp is returned
224 with special ISDS error code 0005. Client can retry to get the same stamped
225 response two times in 20 minutes. Exceeding this quota leads to 50-second
226 delay or error code 3005.
228 If time stamp authority is failing, error code 9502 is returned without any
235 Message checksum is a hashed bit stream of part of a message. Exact message
236 part to hash must preserve physical XML serialization. The hash value is
237 carried inside a message, it's stored in ISDS and it's used as a input form
240 Currently SHA-1 and SHA-256 algortihms are defined. They are identified by
241 dmHash/@algorithm attribute. Algorithm name in attribute value contains hyphen
248 There exists special message type initiated by ISDS (i.e. from system, not
249 from other box). Such message has reserved from-box `aaaaaaa' (7 × `a') value
250 and sender type `0' and it always contains a document of type HTML and
251 sometimes a document of type XML. The XML one provides structured reason of
252 sending the system message, the HTML one is a human-readable form. There are
253 following cases defined:
256 -------------------------------------------------------------------------------
257 1 Outgoing message contained malicious code.
258 2 You, administrator, deleted other user.
259 3 Outgoing message could not been delivered because recipient box had
260 been made inaccessible retrospectively.
261 4 Outgoing commercial message has been deleted before accepting it by the
263 5 User has been added to your box.
264 6 User permissions has been changed.
265 7 Box has been made temporary inaccessible on court desicion (e.g. user
266 has been found eligable unresponsible).
267 8 Box has been made temporary inaccessible on box owner or administrator
269 9 Box has been made permanently inaccessible because organization does
271 10 Box has been made permanently inaccessible because owner has died.
272 11 Personal data of box owner does not match central register.
274 The XML document has following structures:
276 SystemMessage – Attribute `type' is a number of case 1, 3, or 4.
278 + dbIDRecipient – recipient box ID
280 SystemMessage – Attribute `type' is a number of case 2, 5, or 6.
282 + userName – user proper name
284 SystemMessage – Attribute `type' is a number of case 7, 8, 9, 10, or 11.
285 No elements are defined.
288 Notification messages
289 =====================
291 ISDS administrator can send business messages from dedicated box `zzzzzzq'.
292 Such a message contains a PDF document with a notification about business
293 activities of the ISDS administrator. Business activity is e.g. a support
294 for commercial messages.
296 Non-normative: The originating box as well as the message are of type system.
302 Users can allow commercial message receiving explicitly in opposite to
305 User can request to assign permission to send commercial messages. Permission
306 can be assigned by Czech Post. Or sending some commercial messages can be
307 offered and paid by third party. Then user don't need special permission from
308 Czech Post to send the specific commercial message. See PDZInfo service for
309 more details. Commercial recipient can not be searched. Sender must know exact
312 Commercial outgoing message is automatically recognized by ISDS using sender
313 and recipient box type, commercial sending/receiving permission, and OVM
314 message flag. All messages are noncommercial, so called public, except
315 following combinations when the message is considered as commercial:
318 Gross type Commercial sending Gross type Commercial receiving OVM flag
319 ----------------------------------------------------------------------------
320 non-OVM allowed non-OVM allowed any
321 any any non-OVM allowed false
323 When sending message, the commercial status can be refined by @dmType
324 attribute in the message envelope:
327 -----------------------------------------------------------------------------
328 I Commercial message offering paying the response instead of the
329 recipient (so called initiatory message)
331 O Commercial message as a response paid by sender of initiatory message
332 V Noncommercial standard message
334 Incoming message or downloaded sent message can have @dmType attribute in the
335 message envelope with following meaning:
338 -----------------------------------------------------------------------------
339 A Subsidized initiatory commercial message which can pay a response
340 B Subsidized initiatory commercial message which has already paid the
342 C Subsidized initiatory commercial message where the response offer has
344 D Externally subsidized commercial messsage
347 I Initiatory commercial message which can pay a response
348 K Commercial message paid by sender
349 O Commercial message as a response paid by sended of initiatory message
350 X Initiatory commercial message where the response offer has expired
351 Y Initiatory commercial message which has already paid the response
352 Z Limitedly subsidized commercial message
354 Missing @dmType attribute means noncommercial standard message.
356 Relation between initiatory message and reply paid by initiatory message
357 sender is established by an identifier defined in dmSenderRefNumber element of
358 initiatory message and the same value copied into dmRecipientRefNumber element
366 1 Message has been put into ISDS
367 2 Message stamped by TSA
368 3 Message included viruses, infected document has been removed
369 4 Message delivered (dmDeliveryTime stored)
370 5 Message delivered through fiction (dmAcceptanceTime stored)
371 6 Message delivered by user log-in or user explicit request (in case of
372 commercial message) (dmAcceptanceTime stored)
373 7 Message has been read by user
374 8 Message could not been delivered (e.g. recipient box has been made
375 inaccessible meantime)
376 9 Message content deleted (thus can not be obtained on-line)
377 10 Message saved in long term storage (this is optional commercial service)
