  • The IHO S-100 Standard and E-Navigation Information
    e-NAV10/INF/7 e-NAV10 Information paper Agenda item 12 Task Number Author(s) Raphael Malyankar, Jeppesen Jarle Hauge, Norwegian Coastal Administration The IHO S-100 Standard and e-Navigation Information Concept Exploration with Ship Reporting Data and Product Specification 1 SUMMARY The papers describe an exploration in modeling substantially non-geographic maritime information using the S-100 framework, specifically notice of arrival and pilot requests in Norway. The Norwegian Coastal Administration is the National Competent Authority for the European SafeSeaNet (SSN) in Norway and thereby maintains a vessel and voyage reporting system intended for use by commercial marine traffic arriving and departing Norwegian ports. Data used in this system describes vessels, HAZMAT cargo, voyages, and information used in arranging pilotage. Jeppesen and the NCA has developed a product specification (the “NOAPR product specification”) based on the S-100 standard, for a subset of information used in the abovementioned system. The product specification describes the data model for ship reporting and pilot requests. The current version is a “proof-of-concept” intended to explore the development of S-100 compatible data models for non-geographic maritime information. The papers also discuss the use of the Geospatial Information Registry and the NOAPR Model. 1.1 Purpose of the document The product specification [NOAPR] demonstrates the feasibility of modelling ship notice of arrival and pilot requests using the data model compatible with S-100. 2 BACKGROUND The papers are a result of a mutual work between Jeppesen and the Norwegian Coastal Administration within the Interreg project; BLAST (http://www.blast-project.eu/index.php).

Activity: 1. Download Activity9_TypeHierarchy.ai from Canvas and open. 2. Explore the Character Panel. Change case here (CAPS, Camel case, etc.) Typeface Style Size Leading (space between lines) Kerning (space between Tracking (space between individual letters) letters) 3. Pick a typeface. 4. Fill in the business card with your information or fake information. You must include 5 pieces of information. 5. Style the text to create a clear visual hierarchy using using Typefaces, Size, Styling, Case, Tracking, and Leading. Visual Hierarchy: The visual order of elements on your business card or map. Big, bold elements draw your eye and rise to figure. Small, thin elements detract and are pushed into the background. Visual hierarchies layer elements visually and move your eye around a given page. Questions, Tips, and Tricks: How can you draw the eye using type (typeface, size, style, case, tracking, leading)? What do you want to stand out and what should be pushed further into the background? Make a list of elements on your business card and rank them from most important to least important. Style them accordingly. Submit: Export a (.png) of your business card and submit to Canvas.

This includes Visual Basic, C#, and SQL. These standards are based upon the MSDN Design Guidelines for .NET Framework 4. Naming Guidelines This section provides naming guidelines for the different types of identifiers. Casing Styles and Capitalization Rules 1. Pascal Casing – the first letter in the identifier and the first letter of each subsequent concatenated word are capitalized. This case can be used for identifiers of three or more characters. E.G., PascalCase 2. Camel Casing – the first letter of an identifier is lowercase and the first letter of each subsequent concatenated word is capitalized. E.G., camelCase 3. When an identifier consists of multiple words, do not use separators, such as underscores (“_”) or hyphens (“-“), between words. Instead, use casing to indicate the beginning of each word. 4. Use Pascal casing for all public member, type, and namespace names consisting of multiple words. (Note: this rule does not apply to instance fields.) 5. Use camel casing for parameter names. 6.

  • Course Material Filename Conventions
    Course Material Filename Conventions These instructions are intended for academic staff creating new Course Material documents. Filename Conventions are to be used across all subjects in The Source, and for all Course Materials linked to the LMS via The Source. The objective is to standardise the structure of filenames across all materials and all subjects. This will help students after downloading subject documents, so they will see the files sorted by subject code and week. The Source uses a platform called SharePoint, which automatically applies version control so documents do not require the year in the filename. WHAT ARE NAMING CONVENTIONS? 'File names' are the names that are listed in the file directory and that users give to new files when they save them for the first time. The conventions assume that a logical directory structure or filing scheme is in place and that similar conventions are used for naming the levels and folders within the directory structure. This document is intended to provide a common set of rules to apply to the naming of electronic files. The ‘naming conventions’ are primarily intended for use with Windows based software and documents such as word-processed documents, spreadsheets and slide-show presentations. WHY USE THEM? Naming records consistently, logically and in a predictable way will distinguish similar records from one another at a glance, and by doing so will facilitate the storage and retrieval of records, which will enable users to browse file names more effectively and efficiently. Naming records according to agreed naming conventions should also make file naming process easier for staff because they will not have to ‘re-think’ the process each time.

  • CP2032 Casing of Bulkdata Uri Element Name
    DICOM Correction Proposal Status Final Text Date of Last Update 2021/03/25 Person Assigned Steve Nichols ([email protected]) Submitter Name Jouke Numan ([email protected]) Submission Date 2020/02/25 Correction Number CP-2032 Log Summary: Casing of Bulkdata uri element name inconsistent for DICOM XML Name of Standard PS3.18, PS3.19 2020a Rationale for Correction: PS3.19 Table A.1.5-2 specifies lowercase (‘uri’) as the element name for BulkData element child to contain HTTP(S) URI whereas the normative schema in section A.1.6 specifies uppercase (‘URI’). Similar in PS3.18: In F.3.1 text, the lower case ‘uri’ is used to refer to the DICOM XML element but in Table F.3.1-1 containing the example mapping the uppercase (‘URI’) is used. Assuming that the schema is normative, lowercase usage should be changed to uppercase. Discussion: WG-27 22 June 2020 • Intent is for schema to be lowercase, attribute names uid and uuid are lowercase in PS3.19 A.1.5-2 • Bill Wallace commented that uid and uuid resolve to lowercase • Changing UID in A.1.5-2 to uppercase would be a breaking change • WG-27 agreed that upper/lower case conventions should be clarified in a note Correction Wording: Add note to PS3.19 section A.1.1 as follows A.1.1 Usage The Native DICOM Model defines a representation of binary-encoded DICOM SOP Instances as XML Infosets that allows a recipient of data to navigate through a binary DICOM data set using XML-based tools instead of relying on tool kits that understand the binary encoding of DICOM.
