Delivers presentations from mind maps with built-in modes and MS PowerPoint export. Perfect for brainstorming, project planning, meeting management, note taking, and more.”
A circuit diagram makes use of standardized symbols that represent electrical components or devices. It is easier to draw these symbols than drawing the concrete pictures of the components.
The actual components might change appearance as the electronics industry revises them or renders them obsolete. The diagrams describe the way in which the components are connected electrically. There are drawn lines that stand for wires or conductors between the appropriate connection points on the symbols; no particular type of wire or physical distance between components is implied; two components might be separated by a few inches or centimeters or a meter or feet.
ConceptDraw PRO provides templates and samples of technical drawings and engineering diagrams (electrical schematics, digital and analog logic, circuit and wiring schematics and diagrams; power systems diagrams; maintenance and repair diagrams for electronics and electrical engineering; block flow and process flow diagrams, piping and instrumentation diagrams for chemical and process engineering; part, assembly, pneumatic, and hydraulic systems drawings for mechanical engineering).

As mentioned in our earlier post on OAIS workflows, this week we also looked at creating an AIP (Archive Information package). An AIP combines the target object for preservation, along with the metadata necessary to both access and preserve it within an OAIS system. We chose to use a pdf of an Ordnance Survey Map as we felt that this item was a good (nice and simple!) example of a digital item which may require ingest into an OAIS.
It was interesting to get an idea of just how much metadata and information should be recorded alongside the data object itself. What we provided was in no way exhaustive, and there are undoubtedly lots of bits of metadata which fall within the Preservation Description Information which would be specific to context. For example, it may include details of actions which have occurred…
