SNPWG17 decided to make telecommunications complex. That based on the assumption that it would be necessary to provide more specific satellite service information like prefix of different sat services, areas on which specific access codes have to be used to connect tx and rx. The entries here are been made to discuss how it should look like and the possible effects on the current MPA and radio service application scheme.

It has to be considered if SRVHRS can somehow combined with this complex attribute. That would make after office hours number superfluous.

raphael 21:33, 5 May 2014 (UTC): how about generalizing communicationIdentityOutSideWorkingHours to an enumeration accessTime, operatingTimes, or access (?) with the following allowed values:
1: during usual working hours
2: out of usual working hours

This can be used in situations other than communications, and also used if we want to specify something is available or can be used both within and outside working hours.

Shorter camel case names would be better. Also, no one will be able to remember whether it is communications... or communication...

raphael 00:49, 8 May 2014 (UTC): The January 2014 S-101 DCEG defines both "web address" and "telephone number" attributes. More meat for the harmonization discussion.

raphael 01:33, 10 May 2014 (UTC): Let's re-organize CONDET address attributes into a new "address" complex attribute, that will allow multiple delivery addresses too.

ISO 19115:2014 defines class CI_Contact with many similarities to CONDET, and defines a CI_Address type with attributes similar to the CONDET physical/delivery address attributes. I think that is mostly a good idea.

jens 18:11, 12 May 2014 (UTC) I agree with both proposals, the accessTime idea and the idea to make CONDET a address complex attribute. For the latter, should we rename that too or should be proceed with CONDET?

raphael 03:40, 13 May 2014 (UTC): Proposed revised model of CONDET, figure below. I will replace attributes EMAILS and ADRNET with enumerants of telcomService if you insist but I think it would be overloading the concept, makes it difficult to define complex attribute telecommunications, and raises a question about modeling radio communications information with CALNAM and CALSGN attributes. Also ADRNET is a sub-attribute of complex attribute TXTCON.

Suggestions or opinions about the methods used for making more compact diagrams are also invited. If I draw them using the "ordinary" conventions, either some boxes stretch three quarters of the page width, or we get tangles of "wiring diagrams".

jens 09:21, 14 May 2014 (UTC)At first, I like the new diagram very much. It is better to read and better to understand. In fact, I believe even people with no experience would be able to read this.

I think that ADRNET might have only one instance. That confirms your idea of having it still as an extra attribute. Regarding EMAILS I have a slightly different view. It could be that an organisation has several emails and we need to model more than one instance. Email is a data transfer. One can see it academic and say that digital phone is also data transfer but I think nobody would easily adopt that. Thus, I still believe that incorporating email might be a good idea.

draft for Wreck feature class

GEO OBJECT CLASSES

Feature: Wreck

Acronym: WRECKS

Camel case: Wreck

Spatial: point, surface

Simple Attributes: CATWRK; EXPSOU; HEIGHT; QUASOU; CONRAD; REPDAT; STATUS; TECSOU; VALSOU; verticalUncertainty; CONVIS; WATLEV; SCAMAX; SCAMIN;

Complex Attributes: fixedDateRange; name; PeriodicDateRange; SourceIndication; TXTCON;

Associated information object classes: NATINF; RCMDTS; REGLTS; RESDES;

Definition:

The ruined remains of a stranded or sunken vessel which has been rendered useless.

IHO Dictionary - S32

Remarks:

See the S-101 DCEG clauses 13.5.2 and 13.6.1 for general encoding rules.
Specific rules for S-122 (MPA):

• S-122 data sets can encode only Wreck features corresponding to artificial reefs or with status=13 (historic).
• If it is required to encode a restricted area around a historic wreck, it must be done using a Restricted Area feature with attribute category of restricted area = 10 (historic wreck area). In addition, the wreck itself must be encoded as a Wreck feature with attribute status = 13 (historic). (S-101 DCEG (2014 baseline) 13.5.2)
• A subsurface fish aggregating devices (FAD) consisting of a vessel that has been deliberately sunk to form a fish haven should be encoded as a Wreck feature (ref. S-101 DCEG (2014 baseline) 13.6.1).

Distinction:

Depth Area; Hulk; Obstruction; Sounding; Underwater Rock

Justification:
S-101 feature used in S-122 to encode historic wrecks and artificial reefs. Many nations have designated areas around certain wrecks of historical or cultural (e.g., sea graves) importance to protect the wrecks from unauthorised interference (e.g., by diving, salvage, or anchoring). Artificial reefs are often used as fish havens.

draft for Obstruction feature class

GEO OBJECT CLASSES

Feature: Obstruction

Acronym: OBSTRN

Camel case: Obstruction

Spatial: point, curve, surface

Simple Attributes: CATOBS; CONDTN; EXPSOU; HEIGHT; maximumPermittedDraught; QUASOU; REPDAT; STATUS; TECSOU; VALSOU; VERLEN; verticalUncertainty; WATLEV; SCAMAX; SCAMIN;

Complex Attributes: fixedDateRange; name; PeriodicDateRange; SourceIndication; TXTCON;

Associated information object classes: NATINF; RCMDTS; REGLTS; RESDES;

Definition:

In marine navigation, anything that hinders or prevents movement, especially anything that endangers or prevents passage of a vessel. The term is usually used to refer to an isolted danger to navigation, such as a sunken rock or pinnacle.

Remarks:

See the S-101 DCEG clauses 13.6.1 for general encoding rules.
Specific rules for S-122 (MPA):

• S-122 data sets can encode only Obstruction features corresponding to fish havens or artificial reefs (category of obstruction = 5 or 14).
• Features that are considered to be subsurface Fish Aggregating Devices (FAD) must be encoded as Obstruction, with category of obstruction = 5 (fish haven), unless the FAD is a vessel which has been deliberately sunk to form a fish haven, which should be encoded as a Wreck feature. (ref. 13.6.1 S-101 DCEG - April 2014 baseline).

Distinction:

Depth Area; Fishing Facility; Foul Ground; Marine Farm/Fulture; Underwater Rock; Water Turbulence; Wreck

Justification:
S-101 feature used in S-122 to encode fish havens and artificial reefs.

Comment:

The following S-101 attributes are not bound to Obstruction features in the S-122 application schema and should not be encoded in S-122 datasets. Applications should ignore their presence in Obstruction features which are part of S-122 datasets.

• PRODCT product
• NATSUR nature of surface
