OGC Web Map Context Document
π At last, one more possible case of the .CML format employment concerns the data file entity applied by various GIS toolkits, such as WMC client for ArcGIS and gvSIG utilities. Specifically, the following .CML record composition includes the parameters and layers of a respective web map project in XML shape. Therefore, the .CML mechanics allow relevant web map projects to be effortlessly opened and reviewed at different locations and times with the same actual views when the projects were accessed and processed the last time. XML, CML and WMC records are generally employed to store contextual metadata to recreate map views with Web Map Services (WMS) protocol layers on other designated GIS platforms. These .CML items not only embed the data specifications required to display and visually represent a particular map, but they also handle metadata, such as the precise information regarding the WMS server layers in the .CMS map schematic layout and the origin of the .CML container. The WMS, abbreviated from Web Map Service entitlement, protocol has been invented and designed in 1999 by the Open Geospatial Consortium (OGC) non-profit organization.
π Primarily, the .CML layout fits for handling .XML file resources encoded in the form of Chemical Markup Language (CML) specification, a universal technological standard applied to specify various chemical content. Accurately, the .CML entries are composed of descriptions of molecule structures or other chemical informatics resources. As a matter of fact, the following .CML extension subgroup is broadly utilized for archiving and exchanging designated chemical information. In the meantime, the .CML standard adheres and follows precise .DTD requirements that are included into an .XSD schema layout instance. Multiple distinguished revisions and branches of the .XSD schemas have been invented, implemented and deployed since the initial official publication of the .CML approach. The logic and hierarchy of the outcome .CML entry precisely conforms to actual .XML standards and is maintained by all types of software, oriented on chemical analysis and .CML research targets.
π One more additional assignment of the .CML format references to the game file employed by Crazy Machines, a creative physics-based entertainment project in the puzzle genre. Specifically, in this clause the .CML container stores a collection of experiments, which are defined as game levels that are played by the user during the game advancement and walkthrough. In general, the .CML technique grants players an opportunity to group level together in sequences. A custom lab entitled as βMy Labβ can be exploited by the in-game player to create distinctive experiments in the game environment. In My Lab UI, players are offered a chance to export predefined tests and experiments to outcome .CME resources as well as properly import the .CME content. In these circumstances, the players are allowed to share resulting .CML game experiments produced in their lab with other community members. It should be also strictly mentioned that .CML items are ordinarily allocated within \data\labs\ catalog in the installation path of the Crazy Machines distributive package.
π Besides, the .CML constitution may rely on the encrypted file attachments generated by the CryptoMailer client. Each of the certain .CML compound elements consists of a file that has been encrypted by the userβs copy instance of the CryptoMailer package. Precisely, the .CML file samples can be opened and decrypted by recipients that possess a CryptoMailer bundle distributive acquired and preinstalled. It should be also noted that CryptoMailer solution is distinguished by perfect .CML format integration with Thunderbird, Windows Live Mail, and Microsoft Outlook e-mail client utilities, as well as specific webmail toolkits and packages. In the actual moment of time the maintenance and sustainment of the .CML compliant CryptoMailer bundle is entirely terminated and discontinued. Thus, since January 1, 2015 the suite is not available for direct download and acquisition from the home project web-portal. However, you may take a chance to seek for the .CML consistent installer bundle on third-party archive web-storages and give a try to test the trial edition of the suite.
How to open an .CML file?
π The .CML file records are accessible for opening up, review and adjustment by diverse chemical research tools, such as Avogadro, Bioclipse, Open Babel and iBabel. As long as all of the aforementioned solutions are compliant with Windows, macOS, and Linux architectures, you can preinstall the highlighted .CML supported packages on any of the noted environments. Besides, in case the source .CML entry serves for storing experimental collection within Crazy Machines puzzle game, it is recommended to attempt opening the noted .CML extension sample within the game UI to uncover the pinpoint item contents. At last, one more opportune case of the .CML file schema utilization concerns the CryptoMailer bundle, an out-dated utility for encrypting designated e-mail attachments. Finally, in particular occasions the target .CML layout may rely on the GIS tools and services and be composed of the options and layered hierarchy of a .CML web map project. In this precondition, make an effort to use the facilities of gvSIG, MapServer, or WMC Client for ArcGIS package, distributed and shared on the free basement from the project repositories.
