cdx files download Cdx files download. The tools in this repo allow CDX file summarization to a more compact file format which can then be analyzed later on a workstation as opposed to a cluster. There are two file formats that the tools work with: .summary files with the format host.tld > which hold information about 2nd level domains, years and some MIME type info. These are still quite large. files generated by host_year_total.py from the .summary and consumed by overlap.py discard all MIME type info and can also optionnally discard all info about years. These are very compact space-delimited text files. The host_year_total.py can already answer some questions about the amount of data that has been archived by a given archive for a host, but do not hold any information on MIME types anymore. Use to create a summary for one or more CDX files per year with data about videos, images, html, pdf and http vs https sites. This program combines several of these summaries into a single one where each 2nd level domain only appears once. It can also run on a single file where then any duplicate entries for a single 2nd level domain are added together. .summary Output file format. The output file format of cdx-summarize and combine-summary are files with the following structure: By default only the second-level domain is kept and all other host information is discarded so that information from all hosts in a second-level domain is aggregated together into a single entry. The years are determined by the date in the CDX(J) files. The n_ fields are counters of the number of entries with a given MIME-type and the s_ fields are the corresponding sizes of the compressed entries in the WARC files. Only entries with a HTTP status code of 2XX are counted, so redirects and errors etc. are ignored. Example output (the newlines are for clarity): It takes as an input a .summary file as described above and outputs a space-delimited file with only the total URLS and size per 2nd level domain and optionally also per year (by default on) When the options -nototal and -noyear are used together, the output file will just consist of the hostnames present in the .summary file. The same result could be gotten faster and more easily using unix cut as in cut -d' ' -f1 file.summary . This programs computes some measures of overlap over files produced by host_year_total. The overlap is not in terms of individual URLs archived, but rather whether the different archives hold at least some files from the same 2nd level domain and also how many files each archive has and how much the compressed size is. The first number in the array is the count of 2nd level domains that appear in the file. The second is the number of URLs and the third is the cumulative size of the compressed WARC records. For keys with more than one source archive (as in ccfrl AND iafrl in the example), the 2nd and 3rd column are for the first source archive, the 4th and 5th column are for the second source archive. Alternatively the program can be run with the -csv switch and the output will be formatted as CSV for use in your favourite spreadsheet program. Example for a csv output: This works with more than 2 source archives but the output can become a bit unwieldy because a lot of columns need to be output if each combination exists. There is also an open question what it means if for the same 2nd level domain two different archives have a different of data. At this point we have reduced the information present in the input files so much that we cannot tell whether the archives have the same data or different one. Summarizing the MIME Types. MIME Type short intro. There are hundreds of valid MIME Types registered with IANA (Internet Assigned Numbers Authority) and the current list can be viewed at https://www.iana.org/assignments/media-types/media-types.xhtml. While this list is extensive, in reality webservers do not always conform to it and return other strings. Webbrowsers are quite leniant and do still handle the files correctly in most cases. Also, web archives have different levels of information available about MIME types. There are the following: MIME types as specified by the server MIME types as determined by an external utility For example the unix utility file can be run with file -- mime-type to determine some MIME types. DROID can be used to determine MIME types. It depends on each webarchive whether they do the characterisation of the files inside of the WARCs or not. The common MIME types are summarised in that they are grouped into several categories. This is mainly to enable the programs to run with less memory requirements (only the number of entries and sizes per category need to be kept). An added benefit is that then it becomes easier to compare the categories later. The categories used here: The categories are specified in the module mime_counter.py as follows: MIME(s) category rationale text/html application/xhtml+xml text/plain HTML These are counted as "web-pages" by Internet Archive text/css CSS interesting for changing usage in formatting pages image/* IMAGE all image types are grouped together application/pdf PDF Interesting independetly, although IA groups PDFs in "web-page" too video/* VIDEO all videos audio/* AUDIO all audio types application/javascript text/javascript application/x-javascript JS these 3 MIME types are common for javascript application/json text/json JSON relatively common and indicates dynamic pages font/ application/vnd.ms-fontobject application/font application/x-font* FONT Usage of custom fonts. Data sources used. Internet Archive metadata summary service. It's possible to get metadata in JSON format from the Internet Archive using this service: Here with the example of the Top-level Domain (TLD) ".lu". There is unfortunately not that much public information available on how exactly these numbers were calculated. The following information is available in the JSON result: "captures", per year, per MIME-type, probably the number of resources with status 2XX that were captured "new", probably the new domains and hosts captured in the year the metadata was computed "new_urls", per year, per MIME-type, probably the number of new resources with status 2XX that were captured (according to their SURT notation) "timestamp", probably when the summary was last calculated "total", per year, probably the total number of 2nd level domains and hosts that returned resources with a 2XX status. "type", the query type, in this case always tld "urls", per year, per MIME-type, probably the number of resources with status 2XX that were captured and that were unique during that year, according to their SURT notation "urls_total_compressed_size", per year, per MIME-type, the size of the compressed WARC records for "urls" As you can see, there are some unknowns in the data and especially the "total" key seems to be strange, since for the TLD .lu it reports 2285 domains only when the CDX files show otherwise. At the date of writing the timestamp is the 22nd of September 2020, so the data for at least 2020 is incomplete. Using Ilya Kreymer's excellent cdx-index-client, you can download the CDX files from any CDX server that you have access to. Internet Archive CDX server. Using cdx-index-client, you can download the data from the Internet Archive's CDX server which lives at: (http://web.archive.org/cdx/search/cdx) [http://web.archive.org/cdx/search/cdx] There is a good description of the capabilities on (Karl-Rainer Blumthal's archive-it blogpost) [https://support.archive-it.org/hc/en-us/articles/115001790023-Access-Archive-It-s-Wayback-index-with-the-CDX-C-API] Common-crawl CDX files. Again, using cdx-index-client, you can download the CDXJ indexes from the common-crawl. Luxembourg Webarchive CDXJ files. Since I have access to the CDXJ files of the Luxembourg Webarchive, I could run the commands locally. Some CDXJ files from the commoncrawl do not have MIME types. These are only counted in the _other fields. Some dates are also invalid, these lines are ignored. Ingesting into elasticsearch. One way of examiming the summary is to ingest them into elasticsearch and then run analytics on them using Kibana. US EPA.

It is similar to a compact index (.IDX) file, but the leaf nodes at the lowest level of a compound index point to one of the tags in the index. CDX files were introduced in version 2 of Microsoft Visual FoxPro, which is a database management program for Windows. Structural CDX file - Automatically opened and maintained by Visual FoxPro when the table is accessed and requires exclusive use of the table. Non-structural CDX file - Not opened or maintained automatically by Visual FoxPro when the table is accessed and new records are added but does not require exclusive use of the table. NOTE: Visual FoxPro was discontinued in 2007. Programs that open CDX files. CorelDRAW Compressed File. What is a CDX file? File created by CorelDRAW, a vector-graphics editing program included with the CorelDRAW Graphics Suite software package; contains a compressed .CDR drawing file; used to reduce the storage space required for a drawing. CDX files are useful for sending smaller files over email, or for archiving drawings on external media. Programs that open CDX files. Alpha Five Table Index File. What is a CDX file? A CDX file is an index file utilized by Alpha Five, an IDE for web application developers. It contains table index data referenced by Alpha Five to find table records and is created when index fields in the table are defined and intended to order lists in your data file. CDX files can only hold index names up to ten characters long with no spacing and are similar to .DDX, .ALX, and .ASX Alpha Five index files. When backing up your data, verify that the CDX file is being saved as well. Otherwise, when the .DBF and .FPT file data is only restored, the CDX file will hold lists from old data and Alpha Five will have to create new lists for the restored data, which may take time. NOTE: In 2013, Alpha Five became Alpha Anywhere. Common CDX Filenames. [Name of your table].cdx - When a table is created and the index field is defined, the CDX file will be created with the same name as your table. CDX-GT66UPW.

Files U.S. Design Patent For CDX, Are You Surprised? A Honda HR-V dressed up for the occasion, the CDX is a commercial hit for Acura in The Middle Kingdom. 4,496 millimeters long and with a of 2,660 millimeters, the premium tips the scales at 1,494 kilograms and offers a little more than 400 liters of trunk capacity. One engine is available, and that’s the 1.5-liter VTEC Turbo found in other models such as the Civic, CR-V, and Accord. In this application, the four-cylinder direct-injected plant develops 182 PS (180 horsepower) and 240 Nm (177 pound-feet) of torque between 1,900 and 5,000 rpm, adequate figures for a vehicle of this size and heft. Be it front- or all-wheel-drive, the CDX comes with an eight-speed dual-clutch gearbox. Performance isn’t something to write home about (8.6 seconds to 100 km/h for the front-wheel-drive CDX), nor are the dynamic capabilities of the platform. After all, bear in mind the MacPherson strut independent suspension up front is paired with a torsion-beam rear axle. From an official standpoint, Acura doesn’t comment on the matter of U.S. availability for very, very obvious reasons. But the United States Patent And Trademark Office clarifies the matter with design patent number D804,996 S. Filed on December 12, 2017, the patent lays the groundwork for what’s to come, whenever Acura decides to bring the CDX to this part of the world. Other than the generic-looking alloy wheels, the rest of the design mirrors that of the China-spec CDX. Make no mistake about it, but this fellow might boost Acura’s market share by a significant margin if marketed to the right audience. Over in China, the CDX is responsible for doubling the brand’s sales volume in a single year.
